File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum.This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files.
It included a more user-friendly interface than CHKDSK, more configuration options, [2] [3] and the ability to detect and (if possible) recover from physical errors on the disk. This replaced and improved upon the limited ability offered by the MS-DOS recover utility. [4] Unlike CHKDSK, ScanDisk would also repair crosslinked files. [5]
