A checksum is a string of numbers and letters that uniquely identify a particular file regardless of the type, ie .mov, .ari, .dng, .png, .txt. Think of them like a fingerprint; no two fingers have the same fingerprint (nope, not even identical twins!) and no two random files have the same checksum; different files = different checksums. This allows people (obviously with the help of computer applications) to compare checksum values to ensure a 100% exact copy of a file is made when duplicating, or offloading files.
*SIDE NOTE: The ID Number is for that particular computer, this is a great way to keep track of your serial numbers.

This is especially important for those that own multiple licenses of the same application. 153554b96e
