    It contains a list of files and checksums computed from the original
    copies of these files. A checksum is computed by using every single
    byte in the original file, so just changing one bit in one byte of the
    file will result in a different checksum being computed.

    Normally used to verify that files have been received correctly as, if
    you recompute the checksum of the files you have received, the new
    checksums will match the checksums of the original if the files have
    been received error-free.

    Do you mean a .CSV file?  In which case this is a comma separated value file.  I sort of list with a comma after each item.

    A checksum file usually generated with the old winrar program.
    Originally, winrar required the "SFV" file to decode the packed files.
    But now that's no longer needed.

    It was used to determine if the part file is corrupt or not.

    Well yeah, but a checksum is quite short, and there are only
    2^(checksum bits) unique checksums while there are 2^(file bits) unique
    files of the same length, therefore there must be at least
    2^(file bits)/2^(checksum bits) = 2^(file bits - checksum bits) (I think)
    files of the same length that have the same checksum.
