Embodiment
The characteristics of in order to more fully hereinafter understand the embodiment of the present invention and technology contents, below in conjunction with the accompanying drawings
Realization to the embodiment of the present invention is described in detail, appended accompanying drawing purposes of discussion only for reference, is not used for
Limit the embodiment of the present invention.
Fig. 1 for the document handling method of the embodiment of the present invention one schematic flow sheet, at the file in this example
Reason method is applied to client, as shown in figure 1, the document handling method comprises the following steps：
Step 101：System file is parsed, at least following information of the system file is obtained：System
Unite file size, use partial information, unused portion information.
In the embodiment of the present invention, the client can be carried on notebook computer (PC), can also be held
It is loaded in the equipment such as desktop computer, server.
In the embodiment of the present invention, the system file is parsed, obtain the system file at least with
Lower information：The size of system file, use partial information, unused portion information；According to what is obtained
Information, deletes the data of unused portion.
Specifically, system file is a complete binary file, passes through head of the client to system file
Portion is parsed, and parsing is divided into two parts：
Part I is parsed：Obtain the size of system file, using part and unused portion.
Part II is parsed：Analysis has used the file of part, for file content labeled as empty file.
In addition, also creating the image file of this document, the information to retain this document.
In the embodiment of the present invention, it is contemplated that it is often system file that version file, which takes data volume the best part,.
And in system file, most numerical value is 0xFF (labeled as sky), i.e. the files-designated of the overwhelming majority
It is designated as sky.So, client be exactly to the core that system file is compressed will in system file mark for
Empty part is deleted, and in system files, retains the relevant information of its original size.
Therefore, the client of the embodiment of the present invention is also parsed to system file, determine labeled as sky
File.
Step 102：According to the information obtained, the data of unused portion are deleted, with to system text
Part is compressed.
Specifically, parsed corresponding to Part I：Delete the data of unused portion.Corresponding to Part II
Parsing：Delete labeled as empty file.Finally give the system file after compression.
Here, it be can be achieved by deleting the data of unused portion and deleting labeled as empty file to system
File is compressed, the system file after being compressed.System file after compression is relative to before compression
Unite for file, the corresponding space of unused portion has been lacked in data volume and labeled as the corresponding sky in empty part
Between.
Step 103：The system file after compression is sent to user equipment.
In the embodiment of the present invention, the system file after compression is sent to user equipment, by user equipment to pressure
System file after contracting carries out decompression reduction, it is achieved thereby that the down operation of system file.
The system file for downloading a 20MB or so size by prior art needs about 15 seconds, using this
After the technical scheme of inventive embodiments, it is only necessary to can just complete down operation within about 10 seconds, it is seen that download effect
Rate is greatly enhanced.
