There are viruses that change the order of certain bytes in the file (as a rule, in the header), after that the file cannot be opened correctly by the normal program. The consequences of virus attacks can be very diverse: from deleting or blocking access to files or disks, rewriting certain types of files and ending with damage to the storage media itself.
The program corrects logical errors in the header structure and file contents, tries to compensate for the missing fragments, extracts all possible information from the damaged file. Every read or write operation from a disk with the presence of bad sectors leads to an increase in bad segments and loss of fragments of some files. The cause of possible file damage is physical damage to the storage media. After that, the file passes an integrity check and is given to the user. The utility analyzes the content of “corrupted” files and tries to recover parts of files that are missing or overwritten using combinatorial analysis. The cause of damage to the file can partially overwrite its contents, as well as fragmentation of the disk that was deleted. The program reads all possible information from damaged files and offers users a file that has been repaired.Īfter recovering deleted data, some files may not be open for viewing or editing.
