Description
Technical field
The present invention relates to filename generation method and generating apparatus in FAT (File Allocation Table, file allocation table) system, particularly file allocation system.
Background technology
The FAT file system is the file system of a kind of hyperdisk data space of Microsoft's definition, show to manage the whole magnetic disk space by FAT, comprise these 3 kinds of file system of FAT12, FAT16 and FAT32 at present, satisfy the space management of different memory space ranges, base unit in these 3 kinds of file system of FAT12, FAT16 and FAT32 in the FAT table is respectively 12 bit, 16 bit or 32 bit.
In the FAT file system, defined a root directory area (Root Directory Region), be used to store the data item under the root directory.
In the FAT file system, the basic storage cell of root directory area is clauses and subclauses (entry), its structure comprises following field: Name (name of file or catalogue) as shown in Figure 1, Ext (extension name), Attr (attribute), Case, Time_ms (time), Create time (creation-time), Create date (date created), Accessdate (the last visit date), Start cluster HI (high position of the starting cluster in file or catalogue corresponding data district), Modify time (the last modification time), Modify date (the last modification date), Startcluster LO (low level of the starting cluster in file or catalogue corresponding data district) and File size (file size).
The all corresponding entry item of each file, an entry item accounts for 32 byte, and root directory area is exactly enumerating of all entry items, if entry has arrived end, promptly do not had next effectively entry, FAT is by representing the byte0 zero setting of entry the end of entry.
Can find that from the entry structure of directory area traditional FAT is conditional on the length of file, dirname, name is 8 characters, expansion 3 characters by name, i.e. 8.3 naming rules of often saying.FAT supports by the definition of having expanded entry in order to realize name is surpassed the support of the filename of 8 characters, in the present invention, describes for convenient, with its called after long filenames.
FAT sets gradually expansion entry item by the front at regular file entry and stores long filenames, and expansion entry as shown in Figure 2.
In above-mentioned scheme, 8 characters of file or catalogue surpass to(for) name, the FAT file system will be stored its filename or directory name, at first will according to what the entry items of expanding of length computation needs of name, remove to apply for the entry number then, generate the short filename of long filenames correspondence then according to algorithm.
Short filename normally " preceding several characters "+"～"+" numeral " of long filenames constitutes, the short filename corresponding as " The quick brown fox.exe " is " Thequi～1.fox ", if a similar long filenames of title is arranged again, as " The quick brown foxl.exe ", then corresponding short filename is " Thequi～2.fox ".
Can find from above description, in the FAT file system, the scheme realization of short filename in conjunction with long filenames adopted in the storage of long filenames, the meaning that short filename exists is exactly for system compatible, preserve the information such as length, memory location of file simultaneously, long filenames adopts the unicode coding, only is used for the storage file name.
Therefore, store a long filenames, a wherein requisite step generates the short filename of this long filenames correspondence exactly, and all short filenames can not be identical under catalogue.
The storage scheme of above-mentioned long filenames will cause following problem:
Deposit the similar long filenames of a lot of filenames under the catalogue, as: DISC050301.jpg, DISC050302.jpg, DISC050303.jpg, DISC050304.jpg ..., such filename has a general character, is exactly that the title major part is similar, has only the fraction difference.
Above-mentioned several filenames can be according to long filenames standard storage in FAT, and its corresponding short filename is: DISC05～1.jpg, DISC05～2.jpg, DISC05～3.jpg, DISC05～4.jpg ....
And in order to generate short filename and will to guarantee that short filename do not bear the same name, when creating new file, FAT will travel through the filename of the All Files under the current directory, guarantees that with this file do not bear the same name, file under catalogue very for a long time, this process will expend the considerable time.
