(13) whether the file that in determining program 14, user selects loads successfully (program 15), if load unsuccessful, illustrate file that user selects without file type extension and file content also damage, File.Copy () function is now first used to back up file, then by file repair procedure module, file content is repaired (program 16), after file is repaired, return information 8 file reading byte stream, continue the process between executive routine 9 to program 15, circulation like this, until meet the demands.
The principle that realizes of file repair procedure module is front 2 bytes by file reading, and be the character of 16 systems by the content transformation of each byte, 2 characters can be obtained, then these two bytes are had all HeadMark property value phases analogy of two characters successively with the FileMark field in File Format Data storehouse.If there is a character identical, then front 2 bytes of file reading, and the character by the content transformation of each byte being 16 systems, can obtain 2 characters, if the EndMark attribute of FileMark is empty, then do not process.If the EndMark attribute of FileMark is not empty, then by the EndMark attribute phase analogy with two characters of these two bytes with the FileMark in File Format Data storehouse successively, if comparative result is similar, then the first two character of this file is become the character in the HeadMark attribute of FileMark, preserve file after conversion, and add file type extension to this file.
If front 2 bytes of getting file do not meet condition above, then get three bytes, comparative approach during above-mentioned two bytes of analogy compares.Obtain byte number before file like this to increase successively, and then contrast, by that analogy, satisfy condition until have.
Generally, the maximum number of byte got is 25.
(14) if the files loading success of program 15 user selection, corresponding application program is then utilized to load user-selected file content (program 17), and add the file type extension identified in program 9 to the file that user selects, be convenient to identify fast and open this file when next user carries out file operation.(program 18)
The above is only preferred implementation of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
