Disk cleanup                                  

 Use this command to tidy up your disk by deleting unwanted and
 unnecessary files.

 Warning:   Whilst the Disk Cleanup is a very useful and
            powerful utility, use it with care, as once files
            are deleted they are no longer on your computer.

 Choose the sets of files you want to delete by clicking on a
 selection set, or pressing the space bar. The following
 selection sets are available:

 . Temporary files           . Backup files
 . Misc Development files    . README Type files
 . Old AUTOEXEC files        . Old CONFIG files
 . Old Windows INI files     . Windows Std Mode files
 . Product Installers        . Compressed files
 . Custom selection sets

 Choose the Start button to locate all the files which meet
 the selection set criteria.

 A list of the files to be deleted is displayed in a list box
 at the top of the dialog box. You can select or deselect files
 using the Insert key.

 You can also send this list to a file panel by choosing the
 Send to Panel button.

 To view the definition for each of these sets, select the set
 and choose the Define button. The Define Selection Set dialog
 box is displayed. You can modify the definitions for the
 selection sets, or create your own custom sets.
