Simple File Verification or commonly abbreviated as its extension (SFV), is a file checksumming utility.

Discussion

Given a set of source files, SFV utilities can create a text file containing a list of file names and their CRC-32 checksums. If supplied with the SFV file, it can validate the listed files.

There are known exceptions to this rule even if they share the same file extension:

• AC_PREFX.SFV

Identification

A SFV file normally contains a list of files and their CRC-32 checksums. Lines beginning with ;, e.g. ; Generated by QuickSFV v1.51 on 2000-05-14 at 16:52:16 are comments which are ignored by the respective checksumming utility.

Sample files

See custom SFV extension search - Discmaster.textfiles.com for a curated list of files that appears to match the identification listed above.
