What are temporary files?
Apps and your operating system (OS) use temporary files to create time-limited backups or track user sessions. Leftover files from the latest OS upgrade, error reports, installation files, downloads, files in your bin — all examples of temporary files you no longer need.
These files are usually deleted automatically, but that’s not always the case. If your session ended abruptly, your device will keep temp files, in case you need them in the future. Temp files typically aren’t malicious (unless you accidentally downloaded malware and kept it in your download folder), but they still pile up and can affect device performance.
We also recommend deleting temporary files after using a public computer, so nobody can spy on your session.
