    .SYNOPSIS
    Deletes all files and folders in user TEMP folder.

    .DESCRIPTION
    The script deletes all files in the user's TEMP folder only

    .EXAMPLE
    - The user's TEMP folder needs to be cleaned because it has become too large
    - A program has left data in the TEMP folder that causes it to malfunction
    
    .NOTES
    Some programs may place files in the TEMP folder but not lock them. These files will be deleted as well, which may cause a program to malfunction.
    It is preferred to run this script only when a user has closed all applications.
