Reducing File Size: Deleting Clips

[Catriona]

I have a project file which is way too big, and have deleted one of the clips in it to reduce the size (by several Gb). However, the size has not reduced and I wonder if it's still cached somewhere?

Ok, it seems to have fixed itself. It seemed to sort itself out after quitting rather than simply closing the projects in question.
