This forum has been extremely helpful to me and I wanted to share this batch file. It was created by Leonardo (aka Secret_Doom) and I want to thank him immensely for his help. As noted in his file, this batch file will work with both Win98 and WinNT. It compares the files in DIR1 to DIR2. If duplicates are found, it removes the duplicate from each and places it in DIR3. :: ----- :: Author: Leonardo Pignataro (secret_doom@hotmail.com) :: :: Compare filenames from %DIR1% and %DIR2%, place a copy :: of the matches on %DIR3% and delete originals. :: :: Designed and tested under: :: Windows 98 Second Edition and Windows XP Professional :: ----- @echo off if "%1"=="GoTo" GOTO %2 %comspec% /E:2048 /C %0 GoTo start goto eof :start :: Set directories below.

Thanks for the credit. However, the script was modifyed because of post problems (besides, some lines wrapped). Below is the full working script (the script you posted won't do what it should). ===== BATCH SCRIPT BEGIN ===== :: ----- :: Author: Leonardo Pignataro (secret_doom@hotmail.com) :: :: Compare filenames from %DIR1% and %DIR2%, place a copy :: of the matches on %DIR3% and delete originals. :: :: Designed and tested under: :: Windows 98 Second Edition and Windows XP Professional :: ----- @echo off if "%1"=="GoTo" GOTO %2 %comspec% /E:2048 /C %0 GoTo start goto eof :start :: Set directories below.
