1.	Solve : copy a file from source location to backup location with folder named %date%?
Answer» Ran into a subdirectory issue with the \ in the %date% when executing MD "%date%_backup" Is there a way to substitute the \ with - or _ to be supported as a continuos DIRECTORY name instead of it chopping into subdirectories for 26th day and 2009 year C:\test123\Mon 01\26\2009_backup Probably simple, but I'm stumped. ThanksUse the SET string=%string:a=b% replacement method (replace all 'a's with 'b's) or set string=%string:a=% (replace all 'a's with nothing, i.e. delete all the 'a's) US %date% format is Day mm/dd/yyyy e.g. Tue 01/27/2009 I think? So set Mydate=%date:/=-% set Mydate=%Mydate: =-% MAKES %Mydate% equal to Tue-01-27-2009 proof Code: [Select]Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp.
