Abstract
The invention provides an efficient method for compressing a file for the file transmission of an instant communication system and a network storage system. The method is mainly characterized in that compressing and decompressing programs are embedded in user programs of file senders and file receivers of the instant communication system/the network storage system to ensure that the compression/decompression operation of the file is performed automatically and completely transparently by a user. By the method, the user of the instant communication system or the user of a network hard disk system can operate in the same way as that no compression technology is used, but the file transmission time of the instant communication system is greatly reduced and the file uploading and downloading of a network hard disk are greatly accelerated; furthermore, much network hard disk space can be saved.
Description
Technical field
Field under the present invention is the instant messaging and the network storage.
Background technology
The timely transmission of file also is an important component part of instant messaging (IM), but present instantaneous communication system, the QQ of Tengxun for example, Messenger of Microsoft and Yahoo or the like, when it carries out the file transmission, all less than embedded compress technique is provided in user program.When the user carries out file when transmitting, to the file that transmits or do not compress, perhaps use for example Winzip of general compressed software by the user, WinRAR etc. compress packing earlier, and then transmit.
When file transmits when not compressing,, just can spend the long time, thereby make the file transmission very not instant if the file that transmits is bigger or file when many.
When using compressed software earlier the file that will transmit to be compressed packing, then cumbersome when transmitting again, and also the user singly need not be familiar with the use of instant communication software, must be familiar with the use of compressed software.The recipient of file also needs to operate in two steps, must use the PKUNZIP identical with the side of compression.
Also there is similar situation in present network hard disk system, when file is uploaded, does not perhaps compress, and compresses packing by universal compressed software earlier before perhaps transmitting, and uploads again.
When the file of uploading did not compress, the time of not only uploading was long, and the time of its download is also long, and took a large amount of memory spaces.
When the file of uploading compressed packing earlier and uploads, the user need compress packing equally and transmit two kinds of operations, needed be familiar with two kinds of application of network hard disc and compressed software, not only bothered but also time-consuming.If the file of uploading is in order to share the compression/de-compression software that others also must have and the side of uploading is same with others.
If downloaded files is not the whole compressed file bag of uploading, but a part of file wherein, then the user also must decompress to the compressed package on the hard disk server earlier, carries out file again and downloads.This incites somebody to action not only very trouble, time-consuming, and can increase the weight of the load of hard disk server greatly, forms the hard disk server bottleneck easily.
The network storage of Google utilizes its mailbox system to carry out, and does not compress when file is uploaded, and single file does not compress when downloading yet, and when downloading a plurality of file, just carries out ZIP packing compression by mailbox server.Can select file in download flexibly though do like this, and reduce the download time of a plurality of files, not solve slow and the big problem of memory space uploaded of file.
The present invention is exactly the problems referred to above that exist at present in instant messaging and the network hard disc application system, gives the technical scheme that makes new advances, new file compression method.It can make the file transmission in the instantaneous communication system very quick, and transmit leg and recipient's operation is all very simple; Can make the file in network hard disc (network storage) application upload and download, all not only convenient but also quick, and the storage resources of network hard disc is saved in a large number.
Summary of the invention
Content of the present invention comprises following several sections:
1, with operation of the File Compress in the instantaneous communication system and decompression operation, be embedded in file transmit leg and file recipient's the user program, thereby the user is still operated when not adopting compress technique, and making the squeeze operation of file and decompression operation is transparent to the user.
2, each file that the instantaneous communication system desire is sent compresses separately, has compressed one and has just sent one, rather than will send out a batch file that send and compress together and pack, and forms a compressed file bag, sends again.
Whether 3, the file to sending in the instant messaging needs the judgement compressed earlier, to the needs compression with do not need the file that compresses, handles respectively, rather than picture zip compression, compresses packing without exception, or does not compress without exception and only carry out file and pack.Can reduce squeeze operation like this to the taking of system resource as far as possible, be beneficial to the user and carry out other operation simultaneously.
4, for the upload file of network hard disk system, each file has compound extension name: one is common file extension, and another is the extension name of uploading batch.So that file had both optionally carried out the download of one or several file when downloading, also the same transmitting file of pulling on can be downloaded in the lump.

Embodiment
Divide two parts to be specifically described below:
Adopt the execution mode of compress technique when 1, instantaneous communication system carries out file transfer
In the instantaneous communication system file transfer, adopt the implementation method of compress technique to be: ZIP and file gunzip are embedded respectively in the file transmit leg user program and file recipient user program of instantaneous communication system.When the transmit leg user chose the file of desire transmission, embedded condensing routine compressed it earlier, is sent by router again.When the recipient receives file, by embedded gunzip it is carried out decompress(ion) earlier, store again, show.
The operating process schematic diagram that instantaneous communication system file transmit leg adopts embedded compress technique as shown in Figure 1, its operating procedure comprises:
A, user " select desire to send file " from the operating system file catalogue, and they are dragged to desire transmission file window, form one " desire transmission document queue ".
The embedded condensing routine of b, file transmitting terminal is got a file name from desire transmission document queue, judge according to its file extension whether this document need compress.For this reason, need the default file extent list of file names that need not compress in the condensing routine, listing in this tabulation is the file extension of compressed file format, for example: PNG, MP3, zip, RAR or the like.
If the extension name of the file that c got does not belong to above-mentioned tabulation, condensing routine then compresses processing earlier to this document, finish squeeze operation after, again it is carried out file mark and handles.
If the extension name of the file that d got belongs to above-mentioned tabulation, then condensing routine does not compress processing to this document, handles and directly it is carried out mark.
E, embedded condensing routine all carry out mark and handle for through the file of its compression with without the file of its compression.For example: its original file name of mark, the file name after the compression, original length, the file size after the compression, compression algorithm that this document is adopted or the like.
Condensing routine is for the file without its compression, and filename behind the mark and file extension all use its original filename and extension name; For the file that passes through its compression, filename still uses original filename, but file extension then uses the compressed format title of this condensing routine.
For example: an original title is the file of A.PNG, and the native system condensing routine no longer compresses, and then the file name behind the mark still is A.PNG; If an original name is called the file of A.BMP, the embedded condensing routine of native system is SCS, to the employing compression algorithm be PNG, then the title of mark is A.SCS.
F, condensing routine will carry out the desire transmission file name of mark processing and deliver to " document queue to be sent ", repeat the operating procedure of b to f then, and the file in " desire transmission document queue " is got sky.
G, router are got corresponding file and are sent according to the file name in " document queue to be sent ", and the file in " document queue to be sent " all sends and finishes.
In the schematic flow diagram of Fig. 1, be provided with " desire transmission document queue " and " document queue to be sent ", be because the speed of user's select File, the speed that system carries out File Compress and the speed of carrying out the file transmission, all may be different, these two formations are used as Buffer Pool, and these two formations also are the natural interfaces between condensing routine and man-machine interactive operation and condensing routine and the router.
The operating process of Fig. 1 also can be carried out some accommodations, and for example: to the file that desire sends, whether embedded condensing routine does not need the judgement compressed to it, uses certain general lossless compression algorithm that it is compressed without exception; The perhaps batch file that desire is sent, condensing routine to grouping or compress packing by the gross, grouping or send or the like by the gross.
The schematic flow sheet of the embedded compress technique of instantaneous communication system file recipient as shown in Figure 2, its operating procedure comprises:
The file that a, instantaneous communication system file recipient's user program is sent the file transmit leg carry out " file reception " operation, and the title that will receive file is sent into " reception document queue ".
B, file recipient's gunzip carries out file and chooses from " reception document queue ", and judges according to the extension name of file whether it is to need decompress files.
C, when the expansion that the receives file formed file format of the embedded condensing routine of native system by name, then this document is carried out decompression operation, and the file name behind the decompress(ion) is delivered to " document queue continues ".
D, when the extension name that receives file is not the formed file format of the embedded condensing routine of native system, then this document is not carried out decompression operation, and directly this document title is sent " document queue continues ".Repeat b to d step operation then, the file in " reception document queue " is got sky.
E, file recipient's user program, the file name according in " document queue continues " reads, shows corresponding file.
When file transmit operation flow process shown in Figure 1 adopted flexible scheme, file decompression operation flow process shown in Figure 2 also adopted corresponding work-around solution.For example when the file transmit leg compresses without exception to the file that sends, the file recipient does not also carry out the judgement that whether need decompress to the file that is received, and the file that is received is carried out decompression without exception, or the like.
2, network hard disk system adopts the embodiment of File Compress technology
Adopting the mode of File Compress technology in network hard disk system, is with condensing routine and gunzip respectively in the file side of the uploading user program and the file side of download user program of embedded network hard-disk system.When the side of uploading user chose the file of desiring to upload, embedded condensing routine compressed it earlier, is uploaded by user's router again; When file in download is received by download side, carry out decompress(ion) by embedded gunzip earlier, store, show by user program again.
The schematic flow sheet of the file side of the uploading employing compress technique of network hard disk system as shown in Figure 3.Its operating procedure comprises:
A, user select the file name desiring to upload from its operating system file catalogue, it is pulled into desire the upload file window, form " desiring the upload file formation ".
B, embedded condensing routine are got a file name from " desiring the upload file formation ", and judge according to the extension name of this document whether this document is the file that needs compression.For this reason, need the default file extent list of file names that need not compress in the condensing routine, listing in this tabulation is the file extension of compressed file format, for example: PNG, MP3, ZIP, RAR or the like.
If the extension name of the file that c got does not belong to tabulation, condensing routine compresses processing earlier to this document, finishes again it to be carried out mark after the squeeze operation and handle.
If the extension name of the file that d got belongs to above-mentioned tabulation, then condensing routine does not compress processing to this document, handles and directly it is carried out mark.
E, embedded condensing routine all carry out mark and handle for through the file of its compression with without the file of its compression.Its original file name of mark for example, the file name after the compression, original length, the file size after the compression, compression method of employing or the like.
For ease of file in download is selected, can give its compound file extension to upload file.Except common file format extension name, also can add upload the date and batch file extension or the like, the date represents with the date, batch represent with 26 English alphabets, for example:
X. PNG . 090518 A
Y. SCS . 090518 A
Z. SCS . 090518 B
Filename file format date batch
Like this, when the user's download file, he both can select one or several file to download, and also can select the same file of pulling on biography to download in the lump.
F, condensing routine will carry out the title of the desire upload file of mark processing and deliver to " treating the upload file formation ", repeat b to f step then, and the file in " desiring the upload file formation " is all got sky.
G, user's router are got corresponding file and are sent, until treating that upload file has all passed according to the file name in " treating the upload file formation ".
The file that the network hard disc server is uploaded the user is with the stored in file format of compression, like this, file storing space is saved in a large number, and the download time of file is shortened greatly.
Similar to the operating process of Fig. 1, the operating process of Fig. 3 also can have multiple flexible mode, no longer exemplifies.
The operating process schematic diagram of the embedded compress technique in network hard disc file download side, as shown in Figure 4, its operating procedure comprises:
A, by select desiring downloaded files the file directory of network hard disc terminal use this user-accessible from network hard disc;
B, network hard disc server descend to pass to user-selected file;
C, terminal use's program receive operation to the file that network hard disc passes down, and the file name of reception file are sent into " reception document queue ";
D, from " reception document queue ", carry out file by condensing routine and choose, and judge according to the extension name of getting file whether it is to need decompressing files;
E, when getting file is the formed file format of the embedded condensing routine of native system, then this document is carried out decompression operation, and the file name behind the decompress(ion) is delivered to " document queue continues ";
F, when getting file is not the formed file format of native system condensing routine, then it is not carried out decompression operation, and directly this document title is delivered to " document queue continues ";
G, from the document queue that continues, select the file desiring to read, read or carry out other processing by the user.
When the operating process of the network hard disc file side of uploading adopted flexible mode, the operational flowchart of network hard disc file download side also adopted corresponding flexible mode.
The present invention is highly suitable for instant messaging and network hard disc user's telefile transmission.It seems that by a large amount of experiment tests the average transmission rate of instant messaging and network hard disc user's telefile transmission is generally 30KB--60KB/ second under the general networking environment.The file of a 60MB does not compress transmission just needs 16.6 minutes--and 33.3 minutes.And the compression verification that the total hundreds of MB file of multiple conventional computer file type carries out being shown adopt suitable compress technique, the mean pressure shrinkage of computer documents can reach several times, compression speed is about 1MB--5MB/ second.
It seems according to above-mentioned test data, in instant messaging and network hard disk system, adopt embedded compress technique provided by the invention, can significantly shorten the transmission time of file really, reduce its memory space, operate and as not using compress technique convenient; Be far smaller than the transmission time of file in view of the compression time of file, the squeeze operation of embedded condensing routine can place the backstage to carry out fully, also can not influence the user and carry out other operations simultaneously, therefore, embedded compress technique also is fully feasible in instant messaging and network hard disk system.
