Temporary files, or foo files (. TMP), are files created automatically by Windows or a running program, to temporarily store information while a new file is being made.
You can recognize them by the.TMP extension. Most of the time they are created as invisible files and should be deleted when the program is closed.
For instance, whenever you open Excel, a temporary file is automatically created to auto-save your text. You will not be aware of this because the process happens in the background.
After you manually save the document or you close it, there is no need for the temporary file, thus, it will be deleted. But, sometimes these files are not deleted automatically.
However, this is not an issue, but over time your computer will store a lot of temporary files that will occupy your disk space leading to performance issues.
When this happens, you can delete the ones that are not in the use of any software. You can find all the .tmp files in the Temp folder which is included in the Windows folder.
