Files can become corrupted for a variety of reasons including: faulty storage media, errors in transmission, write errors during copying or moving, and so on. SFV allows a person to ensure that a file has not become corrupted by comparing a [[hash]] applied a file to see that they are equal. SFV also allows users to verify the authenticity of files, since if a file was changed (say, with the addition of malliciousmalicious code) the hash 'fingerprint' of the file would change and alter the user that the authenticity of the file is in question.

One of the first programs to use the SFV format was [[WinSFV]].
