Maybe this belongs in the DOS forum.
For about ten years, I've run a "second guess" batch backup program to save changes of some key directory areas, monthly. OS is XP Home. Suddenly, today, the command XCOPY "is not recognized as an internal or external command, operable .." etc. Typical trouble statements in this program today are:
Echo Backing up my current unprocessed downloads.
XCOPY "c:\Download\*.*" E:\Archives\Stash\History\Download /D:%1 /S /V /K
%1 contains the prior backup date from which to copy, usually about a month ago, entered manually at the command prompt.
The batch program has not been changed in years. In this environment, the only suspicion I can see is the few Microsoft updates that I see (and allow to be) automatically applied almost every day recently. Could this be a corruption in my OS? Or what else?
I'm lazy, memory's cheap, and after ten years, I'm happy to live with this code until it dies. Any suggestions on why it suddenly quits would be warmly welcome!
