Step 102：According to default rating conditions to the deletion file divided rank in recovery zone.
Step 103：Handled accordingly according to grade deleting file.
When handling the deletion file in recovery zone, for different grades of file, different processing sides is imposed
Processing is deleted or compressed to the higher file of method, such as In Grade, and the relatively low file of In Grade keeps constant etc..
The default rating conditions can be the attribute specification for deleting file, and the attribute concretely deletes the big of file
Small, type or distance are moved to the information such as the time interval (deleting duration) of recovery zone.For example, on the basis of deleting duration
The division of grade is carried out to deleting file, the longer file of the time interval that recovery zone is moved to apart from file is divided into
Higher grade.Certainly it may also be combined with fileinfo of both deletion duration and file size and drawn to deleting file progress grade
Point, then for different grades of file, different processing methods is carried out, this method taken into account can be to deleting in recovery zone
Except file realizes the management more to become more meticulous.
In addition, because the file that user deletes can be short message, message registration, Office documents, picture, audio, regard
The all kinds such as frequency or APP (Application, application program), and various types of files may to the significance level of user
It is different, it is possible to carry out the division of grade to deleting file according to significance level, then carried out for different grades
Different processing.
E-file processing method provided in an embodiment of the present invention is by by a part of region of electric terminal memory space

Recovery zone is stored, and can prevent that file is lost caused by delete by mistake, is facilitated user to carry out file and is given operation for change.And
Deletion file divided rank of this method also to recovery zone, different processing methods is imposed for different brackets, achievable pair
The fine-grained management of file is deleted, improves the utilization rate of memory space, is avoided because being turned some files using insufficient space
Move to caused trouble on External memory equipment.
Fig. 2 show a kind of flow chart of e-file processing method of another embodiment of the present invention offer.Such as Fig. 2 institutes
Show, this method comprises the following steps：
Step 201：Instruction is deleted according to file file to be deleted is moved into the first recovery zone, turn into deletion file.
In the present embodiment, recovery zone includes the first recovery zone and the second recovery zone, wherein, the first recovery zone
In the internal storage of electric terminal, the second recovery zone is then in the external memory storage of electric terminal.When receiving
When the file of user's triggering deletes instruction, file to be deleted is moved to the first recovery zone by the present embodiment from former storage location.
Step 202：According to the value requirement for the attribute for deleting file to the deletion file divided rank in recovery zone, and
Grade is divided into grade 1, grade 2, grade 3, class 4 and the class 5 five that rank gradually reduces according to the requirement of default attribute value
Individual grade.
Step 203：The deletion file that In Grade is 1 carries out depth-compression, and its compression ratio is W1；In Grade is 2 deletion
File carries out either shallow compression, and its compression ratio is W2；The deletion file that grade is 3 is transferred to the second recovery from the first recovery zone
Region；The deletion file that In Grade is 4 and 5 does not process；Wherein, W2>W1.
I.e. in the present embodiment, rating conditions require to delete the value of the attribute of file, wherein, attribute is included as deleted
The information such as deletion duration, file size or the file type of file.In one embodiment, step 202 specifically includes：Acquisition is deleted
Except the property value of file；According to the requirement of the attribute value of default each grade will delete file be divided to corresponding in grade.
In a specific embodiment, deletion duration and file size that the attribute of file includes deleting file are deleted.
According to the processing of deletion duration and file size to deleting the rule of file 5 grade classifications of progress and being done for each grade
Respectively：
The rating conditions of grade 1 are more than the 3rd duration threshold value, the deletion text that In Grade is 1 to delete the deletion duration of file
Part carries out depth-compression, and its compression ratio is W1；
The rating conditions of grade 2 are between the second duration threshold value and the 3rd duration threshold value to delete the deletion duration of file
And its file threshold value is more than the 3rd file threshold value, the deletion file that In Grade is 2 carries out either shallow compression, and its compression ratio is W2；
The rating conditions of grade 3 are between the first duration threshold value and the second duration threshold value to delete the deletion duration of file
And its file threshold value is more than the second file threshold value, the deletion file that grade is 3 is transferred to the second recovery from the first recovery zone
Region；
The rating conditions of class 4 are less than the first duration threshold value and its file threshold value to delete the deletion duration of file and are more than the
One file threshold value, be all unsatisfactory in recovery zone grade 1, grade 2, grade 3 and class 4 rating conditions deletion file for etc.
Level 5 deletes file, and the deletion file that In Grade is 4 and 5 does not process.
Wherein, the 3rd duration threshold value>Second duration threshold value>First duration threshold value, file threshold value are the threshold of file size
Value, the first file threshold value>Second file threshold value>3rd file threshold value, and W2>W1.
For the first duration threshold value, the second duration threshold value and the 3rd duration threshold value and the first file threshold value, the second file
The concrete numerical value of threshold value and the 3rd file threshold value, those skilled in the art can be according to specific needs or with reference to default recovery areas
The parameters such as the storage capacity value in domain are set, and the present invention is not limited this.
The grade classification rule for the method that the present embodiment provides will be illustrated with numerical example below and according to this rule
What is performed is directed to different grades of different disposal method.
In this example, the first duration threshold value, the second duration threshold value and the 3rd duration threshold value take respectively 72HR, 720HR and
2160HR, the first file threshold value, the second file threshold value and the 3rd file threshold value take 500MB, 250MB and 50MB respectively.
As above, when receiving file and deleting instruction, the first recovery zone that file to be deleted will be moved in recovery zone,
As deletion file.If this file size for being just moved to recovery zone (delete duration and be less than 72HR) is more than 500MB, by
It is divided into class 4 and deletes file, if its file size is less than 500MB (including equal to 500MB), is divided to grade 1-4
Outside class 5 in.So the file size for no matter being just moved to recovery zone is how many, all it can not be processed, and after
Continuation of insurance is stayed in the first recovery zone.
(the time stored in the first recovery zone when deleting the deletion duration of file more than 72HR and being less than 720HR
During more than 72HR), the deletion file more than 250MB is then divided into grade 3 and deletes file, i.e., former class 4 deletes file and big
The larger deletion file of file these file sizes, the time stored in the first recovery zone are deleted in 250MB former class 5
Grade 3 can be upgraded to during more than 72HR and delete file.The processing mode that file is deleted for grade 3 is, by it from first time
Zone-transfer is received into the second recovery zone.That is, storage of first recovery zone for deleting the file short time, second
Recovery zone is then used to delete file (the especially larger deletion file of file) storage for a long time.So, large volume is deleted
File is stored in external memory storage, saves internal storage space so that other application uses.Due to terminal-pair storage inside
The access speed of device is higher than to the access speed of external memory storage, so in terms of some, improves the property of machine system
Energy.
When deleting the deletion duration of file more than 720HR and being less than 2160HR, the deletion file more than 50MB is then divided
File is deleted for grade 2, i.e., former grade 3 deletes file (the deletion file having been transferred in the second recovery zone) and more than 50MB
Former class 5 delete file (the deletion file being still stored in the first recovery zone) as long as the time stored in recovery zone
Grade 2 can be upgraded to during more than 720HR and delete file, the processing mode that file is deleted for grade 2 is then compressed for either shallow, its
Compression ratio is W2.That is, no matter deleting whether file is transferred in the second recovery zone, exceed as long as it deletes duration
720HR and its size is more than 50MB, carries out either shallow compression to it.It should be understood that compression ratio refer to it is big after compressing file
The ratio between small size with before compression, compression ratio is usually the smaller the better, but presses smaller, and decompression time is also longer.So
The deletion file that In Grade is 2 takes either shallow squeeze operation, not only can effectively save memory space, can also need to recover text
Shorten the file access pattern time during part.
It is either much or be stored in deleting for which recovery zone when deleting the deletion duration of file more than 2160HR
File is deleted except file is all divided into grade 1, depth-compression is carried out to it, its compression ratio is W1.That is, this etc.
In the rule of level division, while take into account and delete duration and file size both of these documents attribute information, however, being finally to delete
Duration determines to delete the highest level of file.As long as more than certain duration threshold value, depth will be performed by deleting file
Compression, because the deleted time is longer, the demand that user needs to give for change may be also lower, so compression ratio selection is less than W2
W1, while disclosure satisfy that user's request, also greatly save memory space.For W1 and W2 concrete numerical value, this area
Technical staff can do different choice according to actual conditions, the present invention is not limited this.
E-file processing method provided in an embodiment of the present invention is internally set up in memory and external memory storage respectively
First recovery zone and the second recovery zone, wherein the first recovery zone is used for the storage for deleting the file short time, the second recovery
Region is then used to delete file (the especially larger deletion file of file) storage for a long time.So, large volume deletes file
It is stored in external memory storage, saves internal storage space so that other application uses, improve the performance of machine system.Separately
Outside, method provided in an embodiment of the present invention carries out grade classification according to file attribute to the deletion file in recovery zone, for
Different grades operates corresponding to performing, and improves memory space utilization rate, and for different grades according to different pressures
Shrinkage is compressed, and while effectively saving memory space, has also taken into full account that user's gives demand for change, for deleting duration
Relatively small deletion file carries out either shallow compression, then when needing to recover file, can lift file decompression speed, shorten file
Recovery time.
Fig. 3 show a kind of flow chart of e-file processing method of another embodiment of the present invention offer.In this implementation
In example, the step 201-203 in step 301-303 and embodiment illustrated in fig. 2 is essentially identical, is not repeated to describe.Such as Fig. 3 institutes
Show, the present embodiment further comprises following step 304 and 305 on the basis of embodiment illustrated in fig. 2.
Step 304：Detect whether the free space value B1 in the first recovery zone is less than default first capacity-threshold T1,
And whether the second free space value B2 in recovery zone is less than default second space threshold value T2.
Step 305：When detecting that the free space value B1 in the first recovery zone is less than the first capacity-threshold T1, according to
The order of rank from high to low, corresponding deletion file in the first recovery zone is moved to the second recovery zone, until first
Free space value B1 in recovery zone is more than the first capacity-threshold T1, when the free space value B2 in the second recovery zone is less than
During second space threshold value T2, according to the order of rank from high to low, by corresponding file of deleting in the second recovery zone from second
Deleted in recovery zone, until the free space value B2 in the second recovery zone is more than second space threshold value T2.
Above-mentioned first capacity-threshold T1 and second space threshold value T2 is respectively default first recovery zone and the second recovery
The threshold value of spatial margin in region, it can be done and different set according to real needs, and T1 and T2 value can may not be used with identical yet
Together, such as T1 and T2 can be respectively 40%, the 50% of the first recovery zone and the second recovery zone total capacity, the present invention to this not
Limit.
Because the memory space of the first recovery zone and the second recovery zone is limited after all, even if being carried out to it finely
The management of change, memory space is set to have obtained effective utilization, but after a period of time, the first recovery zone and the second recovery area
Deletion file in domain can also form accumulation, and after reaching to a certain degree, recovery zone can not then accommodate more files again.So
The deletion file in the first recovery zone can be made gradually to be transferred to the second recovery zone by above-mentioned steps 304 and 305, so as to
System is set to keep the operation of high access speed, the deletion file in the second recovery zone reaches after certain threshold value again through scale removal process
To discharge more spaces.It is and above-mentioned to be transferred to the second recovery zone and from the second recovery zone from the first recovery zone
The process of deletion, carried out according to the order of grade from high to low, i.e. the file deleted time is longer, its original size
Bigger, the priority for being transferred or being cleaned from recovery zone is higher.Again because the time that file is put in recovery zone gets over
Long, user may need its probability smaller, and delete the file that duration is longer and/or original document is bigger, easier to be drawn
Divide to higher rank, thus the present embodiment is to consider to delete probability and memory space that file is needed again by user
Saving amplitude handled, embody the design of hommization significantly, improve Consumer's Experience.
The embodiment of the present invention additionally provides a kind of e-file processing unit, as shown in figure 4, the device includes：Mobile mould
