Crime has got to be the greatest disk copier it is possible to get in the public domain. Written by Crown of the Band European News Group (BENG), the actual code for the program is kept as small as possible (8K) for allow for a really big buffer. In fact, a huge 112K is at your disposal for either disc or file copying.
Not only does it have the biggest buffer, but also the fastest copying time. A full disk can be transferred from Drive B to Drive A in about (no more than) thirty seconds. Unfortunately, it does have a minor drawback: It only accepts Data format disks, but other than that if you want to mass produce copies at a startling rate, this is the one for you.
