Quick answer: Videos are often the easiest large personal files to move off C drive after review.
Why this happens
Screen recordings, phone videos, exports, and editing previews can consume far more space than temporary files.
Safe steps
- Sort Videos, Desktop, and Downloads by size.
- Look for MP4, MOV, MKV, AVI, and project export folders.
- Move finished videos to another drive.
- Archive old recordings to cloud or external storage.
- Delete only after confirming backups.
What to avoid
Do not delete source media for active editing projects unless the project is backed up.
