Project > Remove Unused
This will remove all items that are not used on the timeline(s).
Files will be untouched, they will just be removed from the project Bin.
I would like a copy of my entire project in a folder, so that all the files are not used will be sorted out.
My folder of the project takes up 14 Gb of HD and I would have done it less. Can it be done?
You can then use Project Manager.
Select "Collect Files and Copy to New Location" and ensure that "Exclude Unused Clips" is checked.
You will now have two folders:
1. original, with all clips
2. folder with trimmed project and only used clips
Wouldn't it be awesome if there was actually a "Projects" menu option?
Of course there isn't, there's just: File, Edit, Clip, Sequence, Marker, Title, Window, and Help.
