So I have created a video presentation for a project I am working on using Final Cut Pro. I noticed Final Cut Pro creates a default folder in Documents called "Final Cut Pro Documents." This folder contains six additional folders: 1. Audio Render Files 2. Autosave Vault 3. Capture Scratch 4. Render Files 5. Thumbnail Cache Files 6. Waveform Cache Files Is it safe to delete these six folders? I wouldn't otherwise care, but collectively they are taking up 25 GB on my HD. I'm not planning to delete the actual FCP project files and their attached media, but rather the above six folders which appear to be cache...? Do I run any risk of losing my entire presentation if I delete these six folders, or is it simply a matter of just re rendering my project if I delete them?
