How to Delete Temporary Files in Windows 11

Temporary files are created by Windows 11 and installed applications to store short-term data such as installation logs, cache files, update leftovers, thumbnails, and system diagnostics. Over time, these temporary files accumulate and consume valuable disk space, which can slow down your system and reduce available storage.

While temporary files are generally safe, they are not meant to remain permanently on your system. Windows 11 provides built-in tools to safely delete temporary files without affecting essential system components. Regular cleanup helps improve performance, free up storage, and maintain overall system health.

This guide explains how to delete temporary files in Windows 11 using safe and built-in methods.
