Concerned about the size of my .PREL files

Concerned about the size of my .PREL files i deleted all content from one such file and saved. No change in file size. Archived file to a Trimmed folder and found many picture, movie and music items from a completely unrelated project. Any ideas how this happened?

Ah, OK. You're in the Photoshop forum.

Sorry, I'm new to this. I'll try to find my way to the correct place.
