Checksum 1.3 - Checksum is a program that allows anyone to quickly and easily calculate file checksums. Briefly, a checksum is a number calculated for a file by performing some operation on all the characters in the file, such as adding up all the character values and generating a total. A checksum is useful for testing the integrity of a file ﾑ the calculated checksum can either be compared against a previously calculated checksum, or the checksum can be compared against a checksum for a file on another computer. Checksum is the easiest way to compare two files on Macintosh computers (either on the same machine or different ones), to tell if they are identical or not!
