My computer has WinXP-SP2 with all patches up to date. It has three HD each partitioned into two “drives”. I have had a batch file using XXCOPY set in Scheduled Tasks to run twice a week to copy data to a back-up disk for years. Suddenly when the scheduled task ran the command prompt window gave this message for each line which started with xxcopy – “‘xxcopy’ is not recognized as an internal or external command, operable program or batch file.” I tried running the batch file from Windows Explorer – same answer, so I tried changing the file to use XCOPY – same result either from a shortcut or directly in Explorer. Incidentally the batch file includes a “dir” command then “pause” at the end so I can confirm that it all ran as expected. When the not recognised message began to appear the batch file no longer stops at the “pause” command.
Can someone tell me why this is happening and what I can do to restore the functionality.
