Temporary files accumulate from web browsing, app installs, system updates, and more. Left unchecked they waste disk space and can slow your PC. This guide shows simple, safe steps to find and remove temp files on Windows and macOS so you can reclaim space in minutes.
Why remove temp files?

- Improved performance: Fewer files to index and scan.
- Reduced clutter: Easier backups and faster searches.
Quick prep (1–2 minutes)
- Close apps: Quit all programs, especially browsers and installers.
- Backup if concerned: Temp files are usually safe to remove; create a quick restore point on Windows or use Time Machine on macOS if you prefer caution.
