I do a lot of production work and testing on my HP Z800 workstation. Though it’s got a 250 GB C: drive, with a 1 TB video drive where I store all projects and associated video, I started getting messages that I was running out of space on my C: drive. I couldn’t imagine why since I store all the big files on D:, so I started hunting around and noticed 110 GB in my Users folder. Long story short, after searching for about ten minutes, I found 110 GB in an Adobe Common folder.


It turns out that this is where Adobe stores all the temporary files it creates for your projects, which are mostly CFA audio files that can be quite large. My vague recollection was that Adobe stored these in the same folder as the project file, but that was wrong. They’re all on your C drive by default, though of course you can change this in Premiere Pro’s Preferences window, which also contains a Clean button you can use to delete all the files. I did, and now I have 115 GB of free space on drive C:.

I’ve changed my preference to store the media files in D:cache, which will keep my C: drive as uncluttered as possible. If you’re a CS4 producer and you’re running out of space on your C: drive, try the Clean button and changing the location of the cache files to an easier to find folder that’s on your video disk.

I knew there had to be a 'clean' button somewhere, but I just couldn't find it anymore...Thanks for sharing its location!

Hi! I am manually deleting all the media cache files in an external hard drive and it doesnt seem to free up any space, so now, the files are gone, but i cant free up any space

You say manually --- does this mean you used File Manager? What happens when you try it in Premiere Pro as shown in this article?

This article doesn't tell us enough. Here is the solution.

You can change Cache Files and Cache DB to an F:/ drive, but when rendering/editing a video it will continue to eat GB from your C:/ drive (where the project is).

Where is this data?? Look at where your project is - ProjectName/Adobe Premiere Pro Preview Files. Delete this.

How do we change the location of this folder? Go to Project > Project Settings > Scratch Disks

Now re-render your sequence with Sequence > Render Effects/Entire...
