The method according to this invention, when opening or carrying out a certain set files, as shown in Figure 5, its step includes:
1. utilize a microprocessor (CPU) 30 to read the recording medium 40 that is positioned at embodied on computer readable, for example the data of the file header of the set files in Winchester disk drive, floppy drive, dribbling machine or the storer;
2. the file header data in the storing step 1 is in the recording medium 40 of an embodied on computer readable, for example Winchester disk drive, floppy drive, dribbling machine or storer, become a concordance list, in order to the index of inquiring about merged raw file or reading merged raw file to be provided;
When real work, be to find the set files by microprocessor (CPU) 30, be stored in the recording medium 40 of an embodied on computer readable in then the files head being read in, for example Winchester disk drive, floppy drive, dribbling machine or storer, be created as a concordance list, be used for retrieval and quick location, opening or carry out each sub-raw file for application program gets ready, certainly, this action of setting up concordance list also can be carried out when the raw file of a certain appointment is opened or carried out in specific requirement again.
3. according to the raw file relative position that is write down in the file header, point to the true reference position of this raw file that is selected, and read the raw file that is selected; For example: the raw file a2.bmp that read is the content from 20 bytes (byte) of relative position 40 beginnings, at first navigate to the relative position of raw file, know that from index raw file is 40 parts from relative position, so just can read the content of 20 bytes on request.
4. close raw file; And
5. close the set files by microprocessor (CPU) 30, or stop to carry out this set files, and the described recording medium 40 that is stored in an embodied on computer readable of deletion abovementioned steps (2), the concordance list in Winchester disk drive, floppy drive, dribbling machine or the storer for example is to treat unlatching and execution next time.
And step wherein (3) also includes following steps:
Corresponding application software is called out and carried out to step 32 according to obtained raw file type, by microprocessor (CPU) 30;
The raw file that is selected is opened or read to step 33 by this microprocessor (CPU) 30.
Here should note: be to be provided with the user mode of a sign among the raw file title in order to the record raw file, if the access times record value that a certain in principle raw file just is being used then correspondence adds 1, in case this raw file does not re-use, just automatically the access times record value is subtracted 1, when the access times record value is 0, show that just this raw file no longer is used; And
In the disclosed method of the present invention, the relative position of raw file (OP): be the starting position that is used for writing down in the set files of raw file after merging, therefore the calculating of relative position (OP) can have many kinds of diverse ways, except aforementioned by the method that microprocessor determined, also can specify by calculation mode, for example:
If the set raw file number that files comprised is n, then relative position (OP) can be a parameter (P; Parameter) with the file sequence number (Fn of raw file; File Number) value that multiplies each other, that is be: OP=(P * Fn);
In like manner, relative position (OP) can be the value that microprocessor (CPU) gets according to an arithmetic expression computing.
Certain aforesaid relative position (OP), it also can be the reference position relative position each other of merged each raw file, with most the raw files of storing continuously from beginning to end each other is example, because each merged raw file is end to end arrangement in regular turn, therefore for wantonly two raw files of storing continuously each other, the reference position of the latter's raw file is with respect to the relative position (OP) of the former raw file reference position, be exactly the initial relative position of the former raw file and the additive value of the former raw file size, can try to achieve the relative position (OP) of latter's raw file.
Therefore at different computing method, when reading the merging files, just can find raw file to be arranged in the actual location of set files with corresponding method.
By above embodiment explanation, in the time of can understanding the unlatching of the method according to this invention desire or carry out raw file, at first to open the set files of merging, then according to the index information that is comprised in the set files, point out the position of raw file in the set files, the action that it is opened or carries out then.
Therefore by Fig. 7 A, the comparison of 7B, can find method of the present invention and classic method are compared, utilize method desire unlatching of the present invention or carry out a plurality of raw files, also only need to carry out the action of a file opening head, just can obtain the related data of each raw file, further read for computing machine from file header, not only can prevent from also can improve the speed of opening or carrying out files to the stealing of raw file.In the process of whole application program operation, the set files are not always to be in open mode, only when choosing sub-raw file, just open the set files, when the sub-raw file of neither one was selected, system just closed the set files.Like this, if the selected unlatching of a plurality of sub-raw files is arranged simultaneously or when carrying out, efficient can improve.
In addition, with regard to another possible embodiments of method of the present invention, In the view of the user, whole set files are just as transparent, when user's desire is opened some raw files, the user does not also know that this raw file is general files, still a son file of gathering in the files.Whole set files when the user will open or carry out some raw files, at first will obtain a sign by manager by a manager administration, just can open or carry out raw file with this sign later on.With regard to the program of opening or carry out a certain raw file, manager can be sought all set files automatically, if can not find, again to the recording medium of embodied on computer readable, seek chosen raw file, return a sign then and utilize for the user.Certainly the manager at this indication can be a kind of instrument in order to unlatching set files, and it can be used when needed, or a kind of resident program module, to assist the user when needed in order to open the set files.Certainly this explanation only is to illustrate embodiments of the invention, is not in order to limit method of the present invention.
For the problem of above-mentioned existence, the present invention proposes the method that a kind of most raw files are merged into set files, its advantage is;
1. by raw file being reassembled into set files, and at set files start-up portion the method for index information is set, can reaches the effect to the raw file protection. Owing to be that multiple raw file is merged into set files, so can not obtain easily, utilize for others, and open or carry out a certain raw file by set files, the wish of inventing after the method for setting forth is opened merging, be as good as with the mode of general unlatching or execution files, need to not be encrypted and decipher for each sub-raw file, thereby improve execution efficient. In addition, merge the memory space that the set files of finishing can also reduce software.
2. what raw files no matter saving system resource open simultaneously, and operating system only need be distributed the resource of set files to software. Because can open or carry out all raw files after opening the set files, just do not distribute the primary system resource so do not need whenever to open a raw file, thereby saved system resource, on the other hand, in the time of can having a plurality of resources to share same raw file simultaneously, prior art will be opened repeatedly a raw file, and the present invention then only need to open once all the time, thereby greatly saved system resource, improved the execution efficient of software.
3. unlatching or execution speed to software have been accelerated. Because the bibliographic structure of raw file is more complicated, then searching and unlatching or the time of carrying out a raw file are just longer. The present invention has simplified bibliographic structure, make unlatching or execution to all raw files become the action of gathering files to, improved obviously the running speed of software, this is particularly evident in the slow storage medium performance of read or write speed, such as CD, floppy disk etc.
