[comp.sys.ibm.pc] How to protect an MS/PC-DOS file from being copied or the diskette.

djwi@computing-maths.cardiff.ac.uk (D J Williams) (05/19/91)

I would like to know on behalf of a friend how to protect an MS/PC-DOS file

from being copied, or indeed the whole diskette, either 5.25" or 3.5"

Many thanks,
David J. Williams.
