xcopy returns "Invalid drive specification" (w/ out the quotes)The subject error message occurs when using xcopy to a network mapped drive.
Using the xcopy command with the same parameters, only changing the destination to another directory on the C: drive, works fine. (Using the copy option of cut 'n paste also works fine.) How do I get the xcopy command to work successfully so I can include it in a batch file to perform backups across my LAN? Any hint would be appreciated. Thanks! Bill Bill wrote:

Thanks for the post .... dir works fine. Any other thoughts? Bill Show quoteHide quote "Michael W.

Every other computer in the office had no problem with the network path. Another thing you might look at is the route command. Maybe there is an entry in there that is preventing XCopy from working or you need to enter one to allow it to work. Show quoteHide quote > Bill > > "Michael W.

Your hints were helpful and after more fussing, the following now works (using xcopy in an MS-DOS Batch file): xcopy "C:\Docs & Settings\name\My Docs" "\\tgt_laptop\tgt dir" parms For some reason (still not understood) the command fails when using a mapped drive letter for the target_save_location (e.g., Y:).

mapping could change if a different user is running the file or even if the current user has changed the mapping. UNC names are the way to go.
