What Are Windows Temporary File Folders and Their Functions?

Files to Look Out for Before Deleting

Some temporary files have important functions and should not be deleted carelessly without understanding their impact:

1. Temporary System Files

• Temporary files that are used by Windows when running various system processes.
• Some of them are still actively used by the system, so deleting them can cause errors or slow down system performance.
• We recommend that you only remove them through built-in Windows features, such as Disk Cleanup or Storage Sense.

2. Prefetch Files

• Prefetch is a cache file created by Windows to speed up the loading time of frequently used applications.
• Deleting this file is not harmful, but it can cause the app to load a little longer when it is first run after deletion.
