Disk Space Disappears Quickly while using Adobe After Effects
Symptom
You receive frequent warnings that your disk space is above 90% full, or you cannot open or create more files, and you use Adobe After Effects for your projects.
Cause
Adobe After Effects creates temporary files that serve as a preview of your projects while you work. The files are stored in your home space and quickly fill up your disk limit.
Solution
1. Open Adobe After Effects.
2. Choose Edit > Preferences > Media & Disk Cache (Windows) or After Effects > Preferences > Media & Disk Cache (Mac OS).
3. Click Clean Database & Cache to remove conformed and indexed files from the cache and to remove their entries from the database. This command only removes files associated with footage items for which the source file is no longer available.
Important: Before clicking the Clean Database & Cache button, make sure that any storage devices that contain your currently used source media are connected to your computer. If footage is determined to be missing because the storage device on which it is located is not connected, the associated files in the media cache will be removed. This removal results in the need to reconform or re-index the footage when you attempt to use the footage later.
