Quick answer: Adobe media cache and preview files can often be cleaned from Adobe app preferences, not by deleting random project folders.
Why this uses C drive space
Creative apps such as Premiere Pro, After Effects, Photoshop, and Lightroom can store previews, media cache, scratch data, and exports on C.
Safe cleanup steps
- Open the Adobe app that created the cache.
- Find media cache, scratch disk, or performance settings.
- Clean cache from inside the app if available.
- Move scratch disks or cache folders to a larger drive.
- Archive old exports and project previews.
What to avoid
Do not delete project files, catalog files, or source media unless you have verified backups.
