Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart illustrating an electronic document processing method according to an embodiment of the present invention. The electronic file processing method can be suitable for mobile terminals such as smart phones, tablet computers and intelligent wearable devices, and can also be suitable for non-mobile terminals such as desktop computers and all-in-one machines. As shown in fig. 1, the method comprises the steps of:
step 101: and moving the file to be deleted to a recovery area according to the file deletion instruction to form a deleted file.
And presetting a part of area of the storage space of the electronic terminal as a recovery area for storing the files deleted under the instruction of the user, and moving the files to be deleted to the recovery area to form deleted files. It is understood that when the electronic terminal is a mobile terminal such as a smart phone, the storage space may include a storage space of the body and a storage space of the inserted memory card.
And in response to a file deletion instruction triggered by a user, when the file to be deleted is moved to the recovery area from the original storage position, the file attribute information such as the size and the type of the file and the time of moving the file to the recovery area can be recorded at the same time.
Step 102: and grading the deleted files in the recovery area according to a preset grade condition.
Step 103: and carrying out corresponding processing on the deleted file according to the grade.
When the deleted files in the recovery area are processed, different processing methods are applied to the files of different levels, for example, the files of higher level are deleted or compressed, and the files of lower level are kept unchanged.
The preset level condition may be an attribute requirement of the deleted file, and the attribute may specifically be information such as a size, a type, or a time interval (i.e., deletion duration) at which the distance from the deleted file to the recovery area is moved. For example, the deleted file is classified into a higher rank based on the deletion time length, and a file having a longer time interval from the file being moved to the collection area is classified into a higher rank. Certainly, the deleted files can be classified according to the file information in the aspects of deletion duration and file size, then different processing methods are performed on the files in different grades, and the method for considering the consideration can achieve more refined management on the deleted files in the recovery area.
In addition, since the files deleted by the user may be various types such as short messages, call records, Office documents, pictures, audio, video, or APPs (applications), and the importance of various types of files to the user may be different, the deleted files may be classified according to the importance, and then processed differently according to the different grades.
According to the electronic file processing method provided by the embodiment of the invention, a part of the area of the storage space of the electronic terminal is preset as the recovery area, and the file to be deleted pointed by the file deletion instruction is moved to the recovery area for storage in response to the file deletion instruction of the user, so that the file loss caused by mistaken deletion can be prevented, and the file retrieving operation by the user is facilitated. The method also grades the deleted files in the recovery area, applies different processing methods aiming at different grades, can realize the fine management of the deleted files, improves the utilization rate of the storage space, and avoids the trouble of transferring some files to external storage equipment due to insufficient use space.
Fig. 2 is a flowchart illustrating an electronic document processing method according to another embodiment of the present invention. As shown in fig. 2, the method comprises the steps of:
step 201: and moving the file to be deleted to the first recovery area according to the file deletion instruction to form a deleted file.
In this embodiment, the recycling area includes a first recycling area and a second recycling area, wherein the first recycling area is located in an internal memory of the electronic terminal, and the second recycling area is located in an external memory of the electronic terminal. When a file deletion instruction triggered by a user is received, the file to be deleted is moved to the first recovery area from the original storage position in the embodiment.
Step 202: the deleted files in the recovery area are graded according to the value requirements of the attributes of the deleted files, and the grades are graded into five grades of grade 1, grade 2, grade 3, grade 4 and grade 5, wherein the grades are gradually reduced according to the preset attribute value requirements.
Step 203: deeply compressing the deleted file with the level of 1, wherein the compression rate is W1; shallow compression is carried out on the deleted file with the level 2, and the compression rate is W2; transferring the deleted file with the grade of 3 from the first recovery area to the second recovery area; the deleted files with the grades of 4 and 5 are not processed; wherein W2> W1.
That is, in this embodiment, the level condition is a value requirement of an attribute of the deleted file, where the attribute includes information such as a deletion duration, a file size, or a file type of the deleted file. In one embodiment, step 202 specifically includes: acquiring an attribute value of a deleted file; and dividing the deleted files into corresponding levels according to the preset attribute value requirements of each level.
In a specific embodiment, the attribute of the deleted file includes a deletion duration and a file size of the deleted file. The rule for dividing the deleted file into 5 grades according to the deletion duration and the file size and the processing for each grade are respectively as follows:
the level 1 grade condition is that the deletion time length of the deleted file is greater than a third time length threshold value, the deleted file with the level 1 is subjected to deep compression, and the compression rate is W1;
the level 2 level condition is that the deletion time length of the deleted file is between the second time length threshold and the third time length threshold, the file threshold is larger than the third file threshold, shallow compression is carried out on the deleted file with the level 2, and the compression ratio is W2;
the grade condition of grade 3 is that the deletion time length of the deleted file is between a first time length threshold value and a second time length threshold value, and the file threshold value is larger than a second file threshold value, and the deleted file with the grade of 3 is transferred from the first recovery area to the second recovery area;
the level 4 level condition is that the deletion duration of the deleted file is less than the first duration threshold value, the file threshold value is greater than the first file threshold value, the deleted files which do not meet the level conditions of level 1, level 2, level 3 and level 4 in the recovery area are level 5 deleted files, and the deleted files of levels 4 and 5 are not processed.
The third duration threshold > the second duration threshold > the first duration threshold, the file threshold is a threshold of the file size, the first file threshold > the second file threshold > the third file threshold, and W2> W1.
For the first time length threshold, the second time length threshold, the third time length threshold, and the specific values of the first file threshold, the second file threshold, and the third file threshold, those skilled in the art may set the values according to specific needs or by referring to the preset storage capacity value of the recovery area, and other parameters, which is not limited in the present invention.
The following will specifically illustrate the ranking rule of the method provided in this embodiment and the different processing methods for different ranks executed according to this rule by numerical examples.
In this example, the first, second and third duration thresholds take 72HR, 720HR and 2160HR, respectively, and the first, second and third file thresholds take 500MB, 250MB and 50MB, respectively.
As described above, when a file deletion instruction is received, a file to be deleted is moved to the first reclamation area in the reclamation areas to become a deleted file. If the file size just moved to the reclamation area (the deletion duration is less than 72HR) is more than 500MB, it is classified as a level 4 deleted file, and if the file size is less than 500MB (including 500MB), it is classified into level 5 other than levels 1-4. So no matter what the size of the file just moved to the reclamation area is, it can be left unprocessed and remain in the first reclamation area.
When the deletion duration of the deleted files exceeds 72HR and is less than 720HR (namely when the time stored in the first recovery area is greater than 72HR), the deleted files larger than 250MB are divided into deleted files of class 3, namely the deleted files with larger file sizes, namely the deleted files of the original class 4 and the deleted files of the original class 5 larger than 250MB, and the deleted files can be upgraded into deleted files of class 3 when the time stored in the first recovery area is greater than 72 HR. The level 3 delete file is handled by being transferred from the first reclamation area to the second reclamation area. That is, the first recovery area is used for storing the deleted file for a short time, and the second recovery area is used for storing the deleted file (especially, the deleted file having a large file) for a long time. Therefore, the large-size deleted files are stored in the external memory, and the internal storage space is saved for other applications. Because the access speed of the terminal to the internal memory is higher than that to the external memory, the performance of the whole system is improved in some aspects.
When the deletion time of the deleted file exceeds 720HR and is less than 2160HR, the deleted files larger than 50MB are divided into level 2 deleted files, namely the original level 3 deleted file (the deleted file transferred to the second recovery area) and the original level 5 deleted file larger than 50MB (the deleted file still stored in the first recovery area) can be upgraded into the level 2 deleted file as long as the storage time in the recovery area is larger than 720HR, and the processing mode of the level 2 deleted file is shallow compression, and the compression rate is W2. That is, regardless of whether the deleted file is transferred into the second reclamation area, it is lightly compressed as long as its deletion duration exceeds 720HR and its size is greater than 50 MB. It is understood that the compression ratio refers to the ratio of the size of the file after compression to the size of the file before compression, and the compression ratio is generally smaller as better, but the smaller the compression ratio is, the longer the decompression time is. Therefore, shallow compression operation is performed on the deleted file with the level of 2, so that the storage space can be effectively saved, and the file recovery time can be shortened when the file needs to be recovered.
When the deletion time length of the deleted file exceeds 2160HR, the deleted file stored in any recovery area or large is classified into the level 1 deleted file, and the deleted file is deeply compressed, and the compression rate is W1. That is, in this hierarchical rule, two pieces of file attribute information, namely, the deletion time length and the file size, are taken into consideration at the same time, however, the highest level of deleting a file is finally determined by the deletion time length. As long as a certain time length threshold is exceeded, deep compression is performed on the deleted file, and the longer the deleted file is, the lower the requirement of the user to retrieve the deleted file is possibly, so that the compression ratio is selected to be W1 smaller than W2, the requirement of the user can be met, and meanwhile, the storage space is greatly saved. The specific values of W1 and W2 can be selected by those skilled in the art according to the actual situation, and the invention is not limited thereto.
The electronic file processing method provided by the embodiment of the invention is characterized in that a first recovery area and a second recovery area are respectively arranged in an internal memory and an external memory, wherein the first recovery area is used for storing deleted files in a short time, and the second recovery area is used for storing the deleted files (especially the deleted files with larger files) in a long time. Therefore, the large-size deleted files are stored in the external memory, the internal storage space is saved for other applications, and the performance of the whole system is improved. In addition, the method provided by the embodiment of the invention performs level division on the deleted files in the recovery area according to the file attributes, executes corresponding operations according to different levels, improves the utilization rate of the storage space, compresses the deleted files according to different compression ratios according to different levels, effectively saves the storage space, fully considers the retrieval requirement of a user, performs shallow compression on the deleted files with relatively short deletion time, and can improve the file decompression speed and shorten the file recovery time when the files need to be recovered.
Fig. 3 is a flowchart illustrating an electronic document processing method according to another embodiment of the present invention. In the present embodiment, the steps 301-303 are substantially the same as the steps 201-203 in the embodiment shown in fig. 2, and the description is not repeated. As shown in fig. 3, the present embodiment further includes the following steps 304 and 305 based on the embodiment shown in fig. 2.
Step 304: it is checked whether the value of the space available in the first recycling area B1 is less than a preset first space threshold T1 and whether the value of the space available in the second recycling area B2 is less than a preset second space threshold T2.
Step 305: when detecting that the available space value B1 in the first recovery area is smaller than the first space threshold T1, moving the corresponding deleted files in the first recovery area to the second recovery area in the order from high to low according to the level until the available space value B1 in the first recovery area is larger than the first space threshold T1, and when the available space value B2 in the second recovery area is smaller than the second space threshold T2, deleting the corresponding deleted files in the second recovery area from the second recovery area in the order from high to low according to the level until the available space value B2 in the second recovery area is larger than the second space threshold T2.
The first space threshold T1 and the second space threshold T2 are preset thresholds of the remaining space in the first recovery area and the second recovery area, and may be set differently according to specific requirements, and the values of T1 and T2 may be the same or different, for example, T1 and T2 may be 40% or 50% of the total capacity of the first recovery area and the second recovery area, respectively, which is not limited in this disclosure.
Since the storage space of the first recovery area and the second recovery area is limited, even if the storage space is managed in a refined manner, the storage space is effectively utilized, deleted files in the first recovery area and deleted files in the second recovery area are accumulated after a period of time, and after a certain degree is reached, the recovery areas cannot accommodate more files. Therefore, the deleted files in the first recovery area can be gradually transferred to the second recovery area through the above steps 304 and 305, so that the system keeps running at a high access speed, and the deleted files in the second recovery area reach a certain threshold value and then undergo a cleaning process to release more space. The above processes of transferring from the first recovery area to the second recovery area and deleting from the second recovery area are performed in the order from high to low, that is, the longer the time the file is deleted, the larger the original size of the file is, the higher the priority of transferring or clearing from the recovery area is. Moreover, as the longer the time that the file is placed in the recycling area, the smaller the probability that the user may need the file is, and the longer the deletion time is and/or the larger the original file is, the more easily the file is divided into higher levels, so that the embodiment comprehensively considers the probability that the deleted file is needed again by the user and the saving range of the storage space for processing, greatly embodies the humanized design, and improves the user experience.
An embodiment of the present invention further provides an electronic document processing apparatus, as shown in fig. 4, the apparatus includes: the moving module 10a is configured to move the file to be deleted to the recovery area according to the file deletion instruction, so that the file to be deleted becomes a deleted file; the grade dividing module 20a is configured to divide the deleted files in the recovery area into grades according to a preset grade condition; and the grade processing module 30a is used for performing corresponding processing on the deleted file according to the grade.
The electronic file processing device can be suitable for mobile terminals such as smart phones, tablet computers and intelligent wearable devices, and can also be suitable for non-mobile terminals such as desktop computers and all-in-one machines. A part of the area of the storage space of the electronic terminal is preset as a recycling area for storing the files deleted under the instruction of the user, and the files to be deleted are moved to the recycling area by the mobile module 10a to become deleted files.
The preset level condition may be an attribute requirement of the deleted file, and the attribute may specifically be information such as a size, a type, or a time interval (i.e., deletion duration) at which the distance from the deleted file to the recovery area is moved. For example, if the deleted file is classified into a higher rank based on the deletion time length, the ranking module 20a classifies a file having a longer time interval from the time when the file is moved to the recovery area into a higher rank. Of course, the ranking module 20a may also rank the deleted files according to the file information in the deletion duration and the file size, and then the ranking processing module 30a performs different processing methods for the files with different ranks, such as deleting or compressing the files with higher ranks, and keeping the files with lower ranks unchanged, so that the method for achieving this consideration may achieve more refined management for the files in the recovery area.
The electronic document processing device provided by the embodiment of the invention presets a part of the area of the storage space of the electronic terminal as the recovery area, and the mobile module 10a responds to the document deletion instruction of the user to move the document to be deleted pointed by the document deletion instruction to the recovery area for storage, so that the document loss caused by mistaken deletion can be prevented, and the user can conveniently retrieve the document. In addition, the device also grades the deleted files in the recovery area through the grading module 20a, and then the grading processing module 30a applies different processing methods to different grades, so that the deleted files can be finely managed, the utilization rate of the storage space is improved, and the trouble caused by transferring some files to external storage equipment due to insufficient use space is avoided.
In another embodiment of the present invention, the recycling region includes a first recycling region and a second recycling region, wherein the first recycling region is located in an internal memory of the electronic terminal, and the second recycling region is located in an external memory of the electronic terminal. When receiving a file deletion instruction triggered by a user, the moving module 10b moves the file to be deleted from the original storage location to the first recovery area.
In this embodiment, the level condition is a value requirement of an attribute of the deleted file, where the attribute includes information such as a deletion duration, a file size, or a file type of the deleted file. The grade division module 20b divides the deleted files in the recovery area into grades according to the value requirement of the attribute of the deleted files, as shown in fig. 5, the grade division module 20b specifically includes: an acquisition unit 21 configured to acquire an attribute value of a deleted file; and a dividing unit 22, configured to divide the deleted file into corresponding levels according to preset attribute value requirements of each level.
In a specific embodiment, the levels are divided into five levels of level 1, level 2, level 3, level 4 and level 5, the levels of which are gradually reduced according to preset attribute value requirements, and the attributes of the deleted file include deletion duration and file size of the deleted file.
The rule for dividing the deleted file into 5 grades according to the deletion duration and the file size and the corresponding processing of each grade are as follows:
if the deletion time duration of the deleted file is greater than the third time duration threshold value, the level 1 file is classified into the deleted file of level 1 by the classification unit 22, and the level processing module 30b performs depth compression, and the compression rate is W1.
If the level 2 level condition is that the deletion time length of the deleted file is between the second time length threshold and the third time length threshold and the file threshold is greater than the third file threshold, the deleted file is divided into the level 2 deleted file by the dividing unit 22, and the level processing module 30b performs shallow compression, where the compression rate is W2.
If the level 3 level condition is that the deletion time of the deleted file is between the first time threshold and the second time threshold and the file threshold is greater than the second file threshold, the deleted file is divided into the level 3 by the dividing unit 22, and the level processing module 30b transfers the deleted file from the first recovery area to the second recovery area.
If the class 4 class condition is that the deletion duration of the deleted file is less than the first time threshold and the file threshold is greater than the first file threshold, and none of the deleted files in the recycle area that do not satisfy the class conditions of class 1, class 2, class 3, and class 4 are class 5 deleted files, the deleted files are divided into class 4 and class 5 deleted files by the dividing unit 22, and the class processing module 30b does not process the deleted files.
The third duration threshold > the second duration threshold > the first duration threshold, the file threshold is a threshold of the file size, the first file threshold > the second file threshold > the third file threshold, and W2> W1. For the first time length threshold, the second time length threshold, the third time length threshold, and the specific values of the first file threshold, the second file threshold, and the third file threshold, those skilled in the art may set the values according to specific needs or by referring to the preset storage capacity value of the recovery area, and other parameters, which is not limited in the present invention.
The electronic file processing device provided by the embodiment of the invention is characterized in that a first recovery area and a second recovery area are respectively arranged in an internal memory and an external memory of the electronic terminal, wherein the first recovery area is used for storing deleted files in a short time, and the second recovery area is used for storing the deleted files (especially the deleted files with larger files) in a long time. Therefore, the large-size deleted files are stored in the external memory, the internal storage space is saved for other applications, and the performance of the whole system is improved. In addition, the device provided by the embodiment of the invention performs level division on the deleted files in the recovery area according to the file attributes, and the level processing module 30b executes corresponding operations according to different levels, so that the utilization rate of the storage space is improved, and the deleted files with relatively short deletion time are compressed according to different compression rates according to different levels, so that the retrieval requirement of a user is fully considered while the storage space is effectively saved, and the file decompression speed can be improved and the file recovery time can be shortened when the deleted files need to be recovered by performing shallow compression on the deleted files with relatively short deletion time.
Fig. 6 is a schematic structural diagram of an electronic document processing apparatus according to another embodiment of the present invention. The electronic document processing apparatus further includes, on the basis of the embodiment shown in fig. 5: a detecting module 40, configured to detect whether the available space value B1 in the first recycling area is smaller than a preset first space threshold T1, and whether the available space value B2 in the second recycling area is smaller than a preset second space threshold T2; and the space processing module 50 is configured to, when the detection module 40 detects that the available space value B1 in the first reclamation area is smaller than the first space threshold T1, move the corresponding deleted files in the first reclamation area to the second reclamation area in the order from high to low in the order of the levels until the available space value B1 in the first reclamation area is greater than the first space threshold T1, and when the available space value B2 in the second reclamation area is smaller than the second space threshold T2, delete the corresponding deleted files in the second reclamation area from the second reclamation area in the order from high to low in the order of the levels until the available space value B2 in the second reclamation area is greater than the second space threshold T2.
The first space threshold T1 and the second space threshold T2 are preset thresholds of the remaining space in the first recovery area and the second recovery area, and may be set differently according to specific requirements, and the values of T1 and T2 may be the same or different, for example, T1 and T2 may be 40% or 50% of the total capacity of the first recovery area and the second recovery area, respectively, which is not limited in this disclosure.
Since the storage space of the first recovery area and the second recovery area is limited, even if the storage space is managed in a refined manner, the storage space is effectively utilized, deleted files in the first recovery area and deleted files in the second recovery area are accumulated after a period of time, and after a certain degree is reached, the recovery areas cannot accommodate more files. Therefore, the deleted files in the first recovery area can be gradually transferred to the second recovery area through the detection module 40 and the space processing module 50, so that the system can keep running at a high access speed, and the deleted files in the second recovery area reach a certain threshold value and then are cleaned to release more space. And the operations of the space processing module 50 for transferring the deleted file from the first recovery area to the second recovery area and deleting the deleted file from the second recovery area are performed in the order from high to low, that is, the longer the time for deleting the file is, the larger the original size of the file is, the higher the priority for transferring or cleaning the file from the recovery area is. The electronic file processing device designed by the embodiment comprehensively considers the probability of the deleted file being needed again by the user and the saving range of the storage space for processing, greatly embodies the humanized design and improves the user experience.
