Deleting files from sessions

Ok so I'm trying to remove unused and unwanted audio files from my session... I'm dealing ONLY with entire files, not regions..



Under the Clips area on the right hand side, I select "Unused", the files I want to remove from the session are highlighted, and I then select CLEAR.



From there, I'm given 4 options:



1. CANCEL I assume does nothing

2. DELETE delete selected source files permanently from disk

3. MOVE TO TRASH Moves to trash for selected source files, if possible

4. REMOVE Remove selected files from this session.



I select Remove, because while I don't want them associated with this session, I do want to keep them the audio files.



Once that is done, I go to the Save A Copy In, and select Audio Files, but when the copy is made, it copies back in the files that are no longer part of the session. Even if I close the session, move the unwanted files out of the Audio File folder, re-open the session and try again, Save A Copy In STILL wants to copy ALL the files..



I'm pretty sure this is NOT the way PT use to work in the past.



How do I get PT to copy ONLY the audio files associated with this session ?
