A temporary file is automatically being created to store information temporarily when a new file is being created or accessed for modifying its content. The temporary file, also known as a foo file it gets automatically deleted when the program of the file is shut down. In case the temp file(s) are not deleted after the program has been closed, it is safe to delete them manually as they are not needed any more.

Temporary files are very useful as they will keep the information even if there is a sudden halt of the PC and it makes possible to recover data. It is advisable to delete temporary files as they might accumulate in time and slow down your PC’s performance. There can be many types of temporary files like internet files, offline web pages, downloaded program files and others.

New operating systems have a built in utility for cleaning up temporary files automatically. This utility is called Disk Cleanup Wizard and can be accessed by clicking on Start / Programs / Accessories / System Tools / Disk Cleanup. A shorter and quicker way to run this application is to click on Start then Run and type the following command: cleanmgr.

You can select which partition to be cleaned and usually the Disk Cleanup utility will also erase the content of the Recycle Bin or Trash.
