Do you have the Microsoft .NET Framework (version 2 or 3.5) installed? Duplicate Cleaner won't work without it.

This is a bug in 3.0.4 - the boxes are supposed to be automatically checkmarked upon import - it will be fixed in 3.0.5.

Sorry you lost your checkmarks! I've put a note on the bugtracking system to update how this works, or at least make it clearer.

Selection assistant 'undo' is on the upcoming development list already.

Any files that are ignored in the scan are also ignored in the folder compare. For instance if you just scan for *.jpg then any other files (thumbs.db, info.txt, etc) are disregarded in the folder comparison stage also. It will show partial tree matches - usually with a note saying that match is 'co...

You are correct - it won't remove any other files apart from the ones marked in the duplicate files list - even if you marked that folder via the duplicate folder tab.

Can you see the files in the mp3 player in Windows Explorer? If you can then the input folder can be dragged over to Duplicate Cleaner's path list for scanning.
