The Media Cache preferences have a significant impact on overall system performance because this determines where all your media work files will be stored.

Media Cache files and databases are work and temporary files that Premiere uses during editing – for example, audio waveforms and thumbnails – and when sharing media between applications. For best results, these should be stored somewhere other than where media files are stored, though that is not required.

The default settings store these on the boot drive in the Library inside your Home directory, but you can re-point these to any folder on any drive – provided the storage is fast enough. Cache files need to be on fast drive.

  • Media Cache Files. These are the data files themselves. Click the Browse button to store these to a different location. However, changing the location does not move any files that are already stored in the original location.
  • Delete unused media cache files. It is a good idea to delete these if your drive starts to fill up, just regain storage space. This option only deletes cache file that are not being used. Media and project files are not affected.
  • Media Cache Management. This allows you to schedule to automatically delete older cache files. I tend to delete files based upon age, rather than size.

If, by accident, you delete cache files that are being used, or new cache files are needed, Premiere will re-create them automatically.

    Larry et al,

    What _are_ cache files? Do they include render files? What happens if they are missing and does it take as long to recreate as render files? Oh yeah, how much space do they require? Could this be an issue on the boot drive?

      Cache files are work files that Premiere creates in order to edit media. These include render files, thumbnails, waveforms, and other temporary files. They vary in size, depending upon their function. Render files are the same size as project. And, yes, as these build up, they take lots of space.
