CRC32 calculates the 32-bit cyclic redundancy checksum (CRC-32)
of a file and displays it along with other useful file information
in a window. The checksum calculation algorithm used in CRC32 is
exactly the same as that internally used by PKZIP and WinZip, i.e.
the 32-bit CRC values calculated by PKZIP and CRC32 are identical.
Though you can use CRC32 to calculate 32-bit checksums of any file
the real strength and usefulness of CRC32 is in comparing Wave
Sound Files to see if their non-silent music parts are identical.
In particular CRC32 may come in handy when comparing two different
extractions of a CD Digital Audio track to ensure that the
performed digital copy is perfect.
