This little program calculates the CRC (i.e. the Cyclic Redundancy Checksum) of any file. A CRC is a "digital fingerprint" of a file, determined by its contents in their entirety. If even one bit in that file is changed, the CRC will be completely different. Thus, this program gives you the ability to determine whether two files are identical. *Note: to install, right-click on the INSTALL.INF file and click "Install".
