What I mean is all exe files on drive D. Including those in subfolders.

Unless absolutely necessary, it's best not to use things like delims and dir to parse screen output. First, the efficiency is relatively low; second, it's easy to make mistakes. The key to the OP's problem is just using the FOR /R parameter: The following is enough: (actually, the use of delims and dir is unnecessary) C:>for /r d: %a in (.exe) do if exist %a rename %a %~na.ex [ Last edited by GOTOmsdos on 2007-1-15 at 10:54 AM* ]
