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.
Following are some of the scratch disk types:
Folder or disk for video files that you capture using the Capture panel.
Folder or disk for audio files that you capture using the Capture panel.
Folder or disk for video preview files. These files are created when you choose Timeline > Render Work Area, export to a movie file, or export to a DV device. If the previewed area includes effects, the effects are rendered at full quality in the preview file.
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. If the previewed area includes effects, the effects are rendered at full quality in the preview file.
Folder or disk for audio peak files, audio conform files, video index files, and other files Premiere Elements creates to improve performance when reading media files.
Folder or disk for encoded video and audio files that are generated when you create a DVD.
Adobe Premiere Elements places preview files, encoded files, media cache files, and other types within subfolders of the folders you specify for these types. Each subfolder is named for the type of scratch files it contains.
