Problems solved by technology

[0002] During the use of the computer, it is easy to lose files. For example, accidental deletion and virus infection will cause abnormal loss of files.
Some existing data recovery software can scan deleted files and save them. However, these files that seem to have been recovered often cannot be used normally. The reason is that the files recovered after deletion are usually damaged. Data recovery software does not provide a fix for it

Embodiment Construction

[0009] After file loss occurs, first scan the disk to get a list of deleted files, select the file to be restored, read it from the disk into the memory, and store it as a usable file after repair. More specifically, the deleted file is found through disk scanning, the file format is judged by reading the file header information, and the length of the file is determined. This embodiment does not directly scan the entire content of the file. The reason is that, on the one hand, for large files, the scanning time will be very long; The possibility of a computer crash. After scanning, compare the file length recorded in the file header with the actual length. If the integrity of the file is damaged, the actual length does not match the length recorded in the file header.

[0010] Taking the RM file as an example, a typical RM file contains two interleaved media streams (sound and image), each stream is composed of a series of information packets, and the header part and each pac...

Description

technical field [0001] The present invention relates to computer technology, in particular to computer data recovery processing technology. Background technique [0002] During the use of the computer, it is easy to lose files. For example, accidental deletion and virus infection will cause abnormal loss of files. Some existing data recovery software can scan deleted files and save them. However, these files that seem to have been recovered often cannot be used normally. The reason is that the files recovered after deletion are usually damaged. Data recovery software does not provide a fix for it. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a file restoration method, which can completely restore deleted files and return them to normal state. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide a computer file restoration method, which includes scannin...
