About scratch disks

When you edit a project, Adobe Premiere Elements uses disk space to store scratch files for your project. These include captured video and audio, conformed audio, and preview files. Adobe Premiere Elements uses conformed audio files and preview files to optimize performance, allowing real‑time editing, high processing quality, and efficient output. All scratch disk files are preserved across work sessions. If you delete conformed audio files, Adobe Premiere Elements automatically recreates them. If you delete preview files, they are not be recreated automatically.

The scratch disk space required increases as your movie becomes longer or more complex. Choose Adobe Premiere Elements 13 Editor > Preferences > Scratch Disks to view the location of your scratch files.

Types of scratch disks

Following are some of the scratch disk types:

Captured Video

Folder or disk for audio preview files. These files are created when you choose Timeline > Render Work Area command. They are also created when you choose Clip > Audio Options > Render And Replace, export to a movie file or DV device.
