Windows creates temporary files for temporary use. They do not take up much disk space and play an important role in the smooth operation of the system. If you must clean your temporary folders frequently, you can do this using Command Prompt.
The storage path for temporary files created by the Windows operating system is %system%/windows/temp. Temporary files created by users are stored in C:\Users\username\AppData\Local\Temp.
Run this command – %SystemRoot%\explorer.exe %temp%\ to open the Temp folder in File Explorer. Then, press Ctrl + A to select all files and delete them. Or run the command – del %temp%\*.* /s /q to delete these temporary files. CMD can automatically skip any files currently in use but delete the remaining temporary files.

Prefetch files are temporary files created when an application runs on Windows. These files contain information used to optimize program execution, such as the number of times the software was run, the run time, and associated files used by the software.

Step 1: Open Command Prompt in Windows with administrator rights.
Step 2: Enter %SystemRoot%\explorer.exe C:\Windows\prefetch\ in the command prompt window and press Enter. This will open the Prefetch folder in File Explorer.
