Hi gang, This seems to work OK in w2k, but is hardwired for a %~tF output of: 14-11-05 21:34 It ignores the time HH:MM and uses only DD MM YY. :: chk4age.bat @echo off if %1'==' echo we need YYMMDD && goto :eof :main set cutoff=%1 pushd test for %%F in (*.bak) do call :compareDATE %%F popd goto :eof :compareDATE set origFMT=%~t1 set newFMT=%origFMT:~6,2%%origFMT:~3,2%%origFMT:~0,2% if %cutoff% GTR %newFMT% echo older :: DONE Note that it will prompt for usage if a parameter is not given. But if you specify something off-the-wall it will not catch your mistake. If at first you don't succeed, you're about average. M2
