An informative report log is generated after file scanning that provides a list of missing and inconsistent files, as well as, a summary for the archive.
SFV Checker can also concatenate files in the list and rename multi archives on the fly, e.g. Correct file naming for .001, .002, .003 files into .rar, .r00, r01 files.
SFV Checker supports RAR, ARJ, ACE and ALL other Binary/Text file types.
