Premiere Pro December 6, 2018 2 min read

It can be very frustrating to be working on a video project and to see that you’re running out of disk space. This can inhibit you from using the full capabilities of your computer and can even slow down your hard drive and workflow. To avoid these problems, it can be very effective to delete your Premiere Pro cache data every so often. Today, we’re going to show you how to do just that!

Note: This method is exactly the same in After Effects too.

Delete Media Cache Data on a Mac & PC

Thankfully, getting rid of cache data is a very simple process:

  • If you’re on a Mac, simply open up Premiere Pro and go to Premiere >  Preferences > Media Cache.
  • If you’re on a PC, simply go to Edit > Preferences > Media Cache.

From here, click the Clean Unused button and cache data that is not being used in the current project open will be removed and deleted. If you want more control over how to prevent cache data from building up in the first place, you have a few options for that as well.

Below the Media Cache Database section, you have three options:

  1. You can set an automatic delete function that deletes cache files older than a certain age. Typically this is set to delete any cache data older than 30 days, but you can customize it to your liking.  
  2. You can set a maximum data amount that you don’t want your computer to exceed. This way you can make sure your cache data never builds up past a certain amount of your choosing.
  3. Finally, you can also set it to never delete automatically and to simply do it yourself by using the ‘Clean Unused’ button.

While we don’t suggest diving into your computers file library to delete them manually, that is also an option that is available to you. To know where your cache data files are being stored, simply look at the directory under the top section of Media Cache Files and follow it to your file location.

Another reason you might be wanting to delete your cache is because of lag issues. If you happen to be experiencing playback lag in Premiere Pro, we have loads more tips for you to try out.

Time to get back to the creative aspects of video editing and eliminate your cache worries!
