What Are %temp% Files?

The %temp% is a folder in Windows, It is a temporary directory used to store temporary  by the operating system. These files can include data needed during an installation, files created during software updates, and various other temporary files that are intended to be short-lived.

Key Points:

• Performance Boost: Over time, the accumulation of temporary files can slow down your system's performance. Regularly cleaning out the %temp% folder can help keep your computer running smoothly.

• Free Up Space: Temporary files can take up a significant amount of storage space. Deleting these files can free up valuable disk space for more important data.

• Reduce Errors: Some temporary files may become corrupted and cause errors or conflicts with other applications. Cleaning out the %temp% folder can help reduce these issues.

What Are Prefetch Files?

Prefetch files are created by Windows to speed up the boot process and the loading of frequently used applications. These files are stored in the Prefetch folder and are used to optimize the system's performance by caching data that may be needed in the future.

Key Points:

• Optimize Boot Time: Prefetch files help Windows load faster by preloading data needed during the boot process. However, an excess of these files can have the opposite effect and slow down your system.

• Improve Application Launch Speed: Prefetch files can also speed up the launch of frequently used applications by caching necessary data.

• Prevent Clutter: Over time, the Prefetch folder can become cluttered with outdated or unnecessary files. Cleaning out this folder can help maintain optimal system performance.
