How to Clear Temporary Files in Windows

Free up disk space, improve performance, and remove unnecessary files safely.

Introduction

Over time, Windows and installed applications create temporary files to support software installations, updates, web browsing, and day-to-day operations.

While these files are useful when they are first created, many become unnecessary and continue to consume valuable disk space.

Regularly clearing temporary files can help:

• Free up storage space
• Improve system performance
• Remove outdated update files
• Resolve some software and Windows Update issues
