Specific embodiment
To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application
In attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the application, instead of all the embodiments.Based on the embodiment in the application, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall in the protection scope of this application.
Fig. 1 is the flow chart of file compression method in one embodiment.This document compression method is applied to computer equipment
In.The computer equipment specifically can be the terminal console or mobile terminal for supporting IOS system, and mobile terminal specifically can be with hand
At least one of machine, tablet computer and laptop etc..
As shown in Figure 1, in one embodiment, providing a kind of file compression method.The present embodiment is mainly in this way
Applied to illustrating in above-mentioned computer equipment.Referring to Fig.1, this document compression method specifically comprises the following steps:
Step S101 scans the attribute information of multiple files in hard disk if timer timing arrives；
When setting timer timing, the time should avoid too short, it is preferred that timer timing can be arranged
It is at least 10 days, in this way, file is just compressed when being not used at least 10 days or more, is set in this way, being more conducive to saving computer
Standby efficiency and space will cause file constantly to compress if setting time is too short, decompress this circulation, to efficiency and space
It all will cause unnecessary loss.
Step S102 chooses the file to be compressed that attribute information meets preset condition in multiple files；
In one embodiment of the invention, the attribute information includes: the last use moment；
In this step, it can determine in multiple files with the presence or absence of the last using between moment and current time
Time difference be more than preset time period file；If it exists, the last is used into the time between moment and current time
Difference is more than that the file of preset time period is determined as file to be compressed.
Based on the embodiment, the file that can not be used for a long time out with automatically scanning, and compressed automatically.
In another embodiment of the invention, the attribute information includes: compressing file mark；
In this step, it can determine in multiple files with the presence or absence of the file with compressing file mark；If it exists, will
File with compressing file mark is determined as file to be compressed.
The file to be compressed that attribute information meets preset condition is chosen in multiple files, may be implemented quantitatively to be pressed
Contracting avoids the excessive excessive file of first compression, efficiency is caused to decline.
Based on the embodiment, the file for adding compressing mark can be compressed automatically.
File to be compressed is compressed, obtains compressed file by step S103.
In this step, file to be compressed can be compressed in computer equipment standby time section, obtains compression text
Part.Computer equipment standby time section can refer to the period of the rarely needed computer equipment of user.

File under compression, equally may be used.
Fig. 1 is the flow diagram of file compression method in one embodiment.Although should be understood that the process of Fig. 1
Each step in figure is successively shown according to the instruction of arrow, but these steps are not the inevitable sequence indicated according to arrow
Successively execute.Unless expressly stating otherwise herein, there is no stringent sequences to limit for the execution of these steps, these steps can
To execute in other order.Moreover, at least part step in Fig. 1 may include multiple sub-steps or multiple stages,
These sub-steps or stage are not necessarily to execute completion in synchronization, but can execute at different times, these
Sub-step perhaps the stage execution sequence be also not necessarily successively carry out but can be with the son of other steps or other steps
Step or at least part in stage execute in turn or alternately.
The embodiment of the present invention by timer timing then, scan hard disk in multiple files attribute information,
Then the file to be compressed that attribute information meets preset condition is chosen in multiple files, can finally be carried out file to be compressed
Compression, obtains compressed file, the embodiment of the present invention can determine file to be compressed in a hard disk automatically, and press to be compressed
Contracting takes considerable time that energy manually selects compressing file without using person, saves user time, be easy to use.
Above-mentioned file compression method is derived using the technical characteristic of file compression method exclusive rights, and realization is able to solve
The beneficial effect of technical problem proposed in background technique.
In another embodiment of the present invention, a kind of file decompression method is also provided, as shown in Fig. 2, the method packet
It includes:
Step S201 scans the attribute information of multiple compressed files in hard disk if timer timing arrives；
Step S202 chooses the file to be decompressed that attribute information meets preset condition in multiple compressed files；
The attribute information, comprising: file decompression mark；
In this step, it can determine in multiple compressed files with the presence or absence of the compression text with file decompression mark
Part；If it exists, file to be decompressed will be determined as with the compressed file that file decompression identifies.
In practical applications, when compressed file is by use, need that file mark will be used, when timers being waited to trigger
It unzips it, efficiency is avoided to decline.
By the step, can timer timing then, by user add the compressed file of decompression mark from
Dynamic decompression.
The file to be decompressed that attribute information meets preset condition is chosen in multiple compressed files, realization is quantitatively solved
Compression avoids once decompressing excessive excessive file, efficiency is caused to decline.
Choose attribute information in multiple compressed files and meet the file to be decompressed of preset condition, may be implemented it is quantitative into
Row decompression avoids once decompressing excessive excessive file, efficiency is caused to decline.
File to be decompressed is unziped it, obtains file by step S203.
In this step, file to be compressed can be compressed in computer equipment standby time section, obtains compression text
Part.Computer equipment standby time section can instigate the period of the rarely needed computer equipment of user.
The embodiment of the present invention by timer timing then, scan hard disk in multiple compressed files attribute letter
Then breath chooses attribute information in multiple compressed files and meets the file to be decompressed of preset condition, finally can will be wait solve
Compressed file unzips it, and obtains file, can determine file to be decompressed in a hard disk automatically, treat decompression file into
Row decompression takes considerable time that energy manually selects file decompression without using person, saves user time, be easy to use.
Above-mentioned file decompression method is derived using the technical characteristic of file decompression method exclusive rights, and realization can
Solve the beneficial effect of technical problem proposed in background technique.
Fig. 2 is the flow diagram of file decompression method in one embodiment.Although should be understood that the stream of Fig. 2
Each step in journey figure is successively shown according to the instruction of arrow, but these steps are not inevitable according to the suitable of arrow instruction
Sequence successively executes.Unless expressly stating otherwise herein, there is no stringent sequences to limit for the execution of these steps, these steps
It can execute in other order.Moreover, at least part step in Fig. 2 may include multiple sub-steps or multiple ranks
Section, these sub-steps or stage are not necessarily to execute completion in synchronization, but can execute at different times, this
The execution sequence in a little step perhaps stage be also not necessarily successively carry out but can be with other steps or other steps
Sub-step or at least part in stage execute in turn or alternately.
