QuickSFV integrates into the Windows Explorer shell and makes it very easy to verify files. Just double-click on the SFV file and QuickSFV does the rest. QuickSFV also understands several other file verification formats including CRC, CSV, and CKZ. For even quicker verification of SFV files, QuickSFV remembers which files have been previously verified and will skip them in future checks. You can always tell QuickSFV to go back and verify all files again just to be sure.
I use this for my backed up files, creating SFVs just so in the future I can easily check if all the files I used it for are not corrupt. Great for what it is made for, even if it has not been updated for a decade now.
