Embodiment
In order to improve the identification of compressed file, the operating efficiency of user is improved, in the embodiment of the present invention, for compression text
Part with the addition of the function of rapid preview, make user on the premise of not decompressed to compressed file, can smoothly preview it is literary to compressing
The content included in part, so as to make compressed file that there is intuitively identification.
Further description is made to the preferred embodiment of the present invention below in conjunction with the accompanying drawings.
Improve the identification of compressed file so that display is more directly perceived, and user can preview compression text without decompression
Part, the time of decompressing files is saved, improves service speed.
As shown in fig.1, in the embodiment of the present invention, the detailed process that preview is carried out to compressed file is as follows：
Step 100：The compressed file of intelligent terminal for reception transmission is simultaneously preserved.
Specifically, intelligent terminal can receive other-end wirelessly or wired mode transmission compressed file.
Such as, intelligent terminal receives the compressed file of PC transmission by data wire.
And for example, intelligent terminal receives the compressed file of mobile phone other intelligent terminals transmission by MSN.
Step 110：When intelligent terminal determines to occur to specify trigger event for the compressed file preserved, to above-mentioned compression
File is scanned, and the file type for each file for determining to include in compressed file based on scanning result and file type are total
Number.
Specifically, so-called specified trigger event can be according to practical situations and pre- by the developer of intelligent terminal
First set.
For example, the operating gesture specified can be set as trigger event is specified, e.g., the icon of long-press compressed file is (i.e.
Click on duration and exceed given threshold), or, double-click the icon of compressed file.
In another example the multimedia instruction specified can be set to specify trigger event, e.g., it is " pre- that user inputs audio instructions
Look at XX files ".
So that specified trigger event is " long-press " icon as an example, as shown in fig.2, user can pass through in grey hot-zone
" long-press " this operation, to trigger the preview image of intelligent terminal generation compressed file (also known as compressed package).
On the other hand, when being compressed to file, as long as filename is not encrypted, the intelligence of compressed file is obtained
Terminal can be with by being scanned, so as to tentatively know the text for including which type in compressed file actually to compressed file
Part, that is, know the file type of each file, and knows the file that how many kinds of difference file type be present, also known as files classes
Type total number, these information are properly termed as obtaining scanning result, can specifically refer to shown in Fig. 3.
Certainly, only it is to illustrate in Fig. 3, in practical application, user may cannot be directly viewed the scanning result shown in Fig. 3,
Intelligent terminal is voluntarily known, will not be repeated here.
Step 120：Intelligent terminal determines the corresponding default displaying total number of files mesh upper limit of above-mentioned file type total number, with
And the default displaying file subnumber mesh upper limit of each corresponding file type is determined respectively；Wherein, each displaying file subnumber mesh
Upper limit sum is the above-mentioned displaying total number of files mesh upper limit.
In the embodiment of the present invention, different file type total numbers corresponds to the different displaying total number of files mesh upper limits, because
File type is more, corresponding to show that the total number of files mesh upper limit be fewer in order to save the generation time of preview image, without
Under same file type total number, each file type corresponds to different displaying file subnumber mesh respectively again, wherein, it is each
The summation of the displaying file subnumber mesh upper limit corresponding to file type is the displaying total number of files mesh upper limit.
Specifically, when performing step 120, can be in the following ways：
First, the file type total number of each file included in compressed file is determined；
Secondly, it is determined that the corresponding file type total number is default to show the total number of files mesh upper limit, and determine respectively
The corresponding default displaying file subnumber mesh upper limit of each file type, wherein, each displaying file subnumber mesh upper limit sum is
The displaying total number of files mesh upper limit.
Below by four kinds of situations respectively exemplified by step 120 is described in detail.
Situation one：File type total number in compressed file is 1 (only existing a kind of file type), then,
Determine that displaying total number of files mesh upper limit is N1 corresponding to it, it is assumed that N1=8 (is only for example).
And displaying file subnumber mesh upper limit M1 corresponding to file type is further confirmed that, in the embodiment of the present invention, due to
Only a kind of file type, therefore M1-N1=8.
If number of files present in compressed file is more than M1, selects M1 and be shown, optionally, can be according to text
The part date of formation is ranked up, and selects the M1 file generated preview image that the date of formation is nearest.
For example, refering to shown in Fig. 4 A, intelligent terminal determines only to include folder type inside compressed file according to scanning
Multiple files, and number of files is more than 8, then 8 files of file generation previews that intelligent terminal can show date nearest
Image.
On the other hand, if number of files is less than 8, preview image can be generated based on whole files.
In another example refering to shown in Fig. 4 B, intelligent terminal determines only to include picture/mb-type inside compressed file according to scanning
Multiple files, and number of files is more than 8, then 8 pictures of file generation preview graphs that intelligent terminal can show date nearest
Picture.
On the other hand, if number of files is less than 8, preview image can be generated based on whole pictures.
Situation two：The file type total number present in compressed file is more than 1 (i.e. in the presence of two and the file of the above
Type), it is determined that displaying total number of files mesh upper limit is N2 so corresponding to it, it is assumed that N2=N1=8 (is only for example), certainly, N2
Value can also be different with N2, such as N2=10, in the embodiment of the present invention, for convenience of description, only said by taking N2=8 as an example
It is bright.
And further confirm that the displaying file subnumber mesh upper limit corresponding to each default file type.
For example, it is assumed that file is not present in compressed file, but contain document, video, audio, picture and installation
Bag, it is assumed that M1a=2 corresponding to document, M1b=2 corresponding to video, M1c=2 corresponding to audio, M1 corresponding to pictured=2, peace
M1 corresponding to dress bage=2, wherein, M1a+M1b+M1c+M1d+M1e=N2=8.
By taking a kind of file type (e.g., video) as an example, if video number present in compressed file is more than M1b, select
M1b are shown, and optionally, can be ranked up according to the file generated date, select the M1b file that the date of formation is nearest
Generate preview image.
If video number present in compressed file is less than M1b, selects whole videos and be shown.
In another example refering to shown in Fig. 4 C, it is assumed that file in compressed file both be present and file is not present, but contained text
Shelves, video, audio, picture and installation kit, it is assumed that M1a=2 corresponding to document, M1b=2 corresponding to video, M1c corresponding to audio
=2, M1 corresponding to pictured=1, M1 corresponding to installation kite=1, wherein, M1a+M1b+M1c+M1d+M1e=N2=8.
By taking a kind of file type (e.g., video) as an example, if video number present in compressed file is more than M1b, select
M1b are shown, and optionally, can be ranked up according to the file generated date, select the M1b file that the date of formation is nearest
Generate preview image.
In another example refering to shown in Fig. 4 D again, it is assumed that existing file has document, video, audio, figure inside compressed file
Piece and installation kit, it is assumed that M1 corresponding to filex=2, M1a=2 corresponding to document, M1b=1 corresponding to video, audio are corresponding
M1c=1, M1 corresponding to pictured=1, M1 corresponding to installation kite=1, wherein, M1x+M1a+M1b+M1c+M1d+M1e=N2=
8。
By taking a kind of file type (e.g., file) as an example, if video number present in compressed file is more than M1x, then choose
Select M1xIt is individual to be shown, it optionally, can be ranked up according to the file generated date, select the M1 that the date of formation is nearestxIndividual text
Part generates preview image.
If file number present in compressed file is less than M1x, then select whole videos and be shown.
Certainly, above-mentioned N1, N2, M1 etc. value are only for example.In practical application, under different application scene, may be used also
According to different file type total numbers, to set the different displaying total number of files mesh upper limits, and each file type to correspond to
The displaying file subnumber mesh upper limit, optionally, displaying the total number of files mesh upper limit value can be with file type total number
Increase and reduce, so perform, also for the further operating time for saving generation preview image.
For example, if file type total number is 1, the displaying file upper limit total number being correspondingly arranged is 8.
In another example if file type total number is 2, then the displaying file upper limit total number being correspondingly arranged is 7.
In another example if file type total number is 3, then the displaying file upper limit total number being correspondingly arranged is 6.
In another example if file type total number is 4, then the displaying file upper limit total number being correspondingly arranged is 5.
……
Step 130：Intelligent terminal is respectively according to the file subnumber mesh upper limit is shown corresponding to each file type, corresponding
File type lower part decompresses the file of respective number, generates corresponding preview image.
It is specifically, (intelligent when performing step 130 exemplified by hereinafter referred to as file type x) by any one file type
Terminal can judge whether the number of files under file type x reaches the corresponding displaying file subnumber mesh upper limit (e.g., 8)；
If so, then intelligent terminal is based on the displaying file subdata upper limit, the file of respective number is selected under file type x
File name decompression, and the file name based on acquisition and the icon for characterizing file type x are at least carried out, generation is corresponding pre-
Look at image.
Otherwise, whole files is selected under file type x and at least carries out file name decompression, and the text based on acquisition
Part title and the icon for characterizing file type x, generate corresponding preview image.
In the embodiment of the present invention, each file type can be corresponded in advance corresponding icon, identical file type are set
Under need to show if there is multiple files, then allow multiple files to use same icon, and pass through the file after decompression
Title is distinguish between.
For example, refering to shown in Fig. 4 A, it is assumed that file type x is file, then can obtain the icon of default file
(file pattern i.e. as shown in Figure 4 A), the file name of each file obtained for decompression mix corresponding file
The icon of folder, so as to generate corresponding preview image.
Optionally, different file types can correspond to different default icons, referring particularly to shown in Fig. 4 C and Fig. 4 D.
Further, by under file type x any one file (exemplified by hereinafter referred to as file x), to file x at least
File name decompression, and the file name based on acquisition and the icon for characterizing file type x are carried out, generates corresponding preview graph
During picture, intelligent terminal can use but be limited to following two modes (being only for example)：
First way is：File name decompression is carried out to file x, and obtains the default icons of respective file type x,
File name and icon based on acquisition generate corresponding preview image.
When using first way, intelligent terminal does not differentiate between file content, and the file of any content is using default
Icon generates preview image.
The second way is：Judge whether file type x is file types
If so, then carrying out file name decompression to file x, and file x partial document data are decompressed
Corresponding icon is generated, and corresponding preview image is generated based on acquisition file name and icon；
Otherwise, file name decompression is carried out to file x, the default icons of respective file type x is obtained, based on filename
Claim and icon generates corresponding preview image.
When using the second way, intelligent terminal distinguishes file content, for the file of some file types
(e.g., image), in order to make user more clearly visible know file content, intelligent terminal can decompress partial document data,
To obtain the icon generated by partial document data, so as to make the icon of generation more targeted.
For example, it is assumed that intelligent terminal determines that file x file type x is file types, i.e. image, then intelligent terminal
In addition to being decompressed to file x file name, it can also be decompressed for partial document data, obtain low resolution
The image of rate, so as to combine file x file name, generates corresponding preview image as icon corresponding to file x.
Certainly, the file of alternative document type, e.g., video, document etc., filename can also be based on using same way
Claim and partial document data generate corresponding image, this is no longer going to repeat them.
Based on above-described embodiment, after generating into preview image, further, intelligent terminal can be directed to each preview
Image is ranked up.
In the case of the first, refering to shown in Fig. 4 A and Fig. 4 B, for preview image corresponding to the file of identical file type,
Intelligent terminal is ranked up according to the order of default displaying priority from high to low.
And so-called displaying priority, can be the priority set on date based on file optionally, i.e. date distance
The displaying priority of the nearest file of current time is higher.
In the case of second, refering to shown in Fig. 4 C and Fig. 4 D, for preview image corresponding to the file of different file types,
Intelligent terminal is ranked up according to the order of default file type priority from high to low.
And so-called file type priority, can be the priority that administrative staff pre-set, e.g., file->Text
Shelves->Video->Audio->Image->Installation kit.
Based on above-described embodiment, as shown in fig.5, in the embodiment of the present invention, a kind of device of preview compressed file is (e.g.,
Intelligent terminal), including at least scanning element 50, determining unit 51 and generation unit 52, wherein,
