MCOPY Makes Multiple Copies

by Benjamin R Cohen

Every time I start using another Eric Meyer utility I marvel at how neatly he has done a job that is needed. MCOPY makes multiple copies of a single file, a task that I perform with some regularity because of my desire to make multiple backup copies of files. I've used (and still use) a lot of different programs, for this, but Eric's MCOPY does something that the others don't do: it copies the file into a memory buffer and then copies it from there to as many different drives as you want That means that if you want to make three copies of the file it has only to be read into memory once from the disk.

MCOPY is just 1K bytes, a typical Eric Meyer assembly language effort: no more size than is absolutely necessary. That's a mixed bag: Eric's utilities offer no help if you don't know what to do. MCOPY's only real deficiency is that it doesn't recognize user areas.

On a system with about 51.5K TPA I was able to copy a test file of 51K bytes! Tested on a file of 55K bytes, MCOPY (not surprisingly) hung the system and I had to reset.
