The sfv file extension is commonly used for simple file verification. It contains a list of filenames and checksums. The sfv file is used to verify files transferred via CD, DVD, USB, etc. The checksum changes if any character in a file is added or removed. So it uniquely identifies files. Programs that support sfv file extension use CRC32 to verify data integrity. Sfv files identify files with mismatched checksums. But they cannot verify authenticity. They are often used when burning disks or downloading files. You can view sfv files in text editors to see filenames and checksums. Or use a checksum utility. Popular software supporting sfv includes QuickSFV. It is associated with the simple file verification format.
