hkSFV is the simply the easiest, most intuitive and automatic way
to create or check .SFV and .MD5 files. And, of course, it's completely free.
What is an .SFV? -- An .SFV file is a tiny list of files and CRCs, which
allow you to check to see if the files you have downloaded are exactly
what you are expecting. The CRC algorithm used in .SFV files allows you
to see if the file you have has been changed, even a single byte, since
the .SFV file was created.
What is an .MD5? -- In a sense, .MD5 did not exist until now, as md5sum is a popular Unix format similar to .SFV and Unix does not use file extensions the way Windows based systems do. .MD5 uses the md5 algorithm to compute its checksums, rather than the crc32 method used by .SFV. The md5 algorithm is almost as fast as crc32, but it is much more accurate at detecting changes in files.
If you need to ensure that your data or data you download is error free, this program is for you.
