How To: Locate All Duplicate Files
To locate all duplicate files present in the system you can use dupfinder.exe [Duplicate File Finder], which is part of Windows Support Tools.
Windows Support Tools is on the XP CD.
Drive:\SUPPORT\TOOLS
Double click on setup.exe and all the tools will be installed under your Program Files folder.
After that do the following:
Start>Run>type in dupfinder>OK
You will now get a GUI. Select the drive on Search in folder(s) tab. You may include your search in subfolders too. Now finally click on Start Search tab. It will scan the hard disk for duplicate files. But for safety don't delete them immediately, rather rename them.
