The Clean Up tool was introduced with Win98 to automate the procedure of cleaning up unnecessary temporary files. It is mainly for people who is having a hard time figuring out what they have on their drives. It has been updated in WinMe/2k/XP, where it is possible to setup different Clean Up profiles.
To configure a profile run the following command (Where N is a profile number from 0-65535):
cleanmgr /sageset:N
To run a configured profile number (N) run the following command:
cleanmgr /sagerun:N
This can be used to create a shortcut to clean up Temporary Internet Files, or schedule a weekly cleanup of the Recycle Bin using the Task Scheduler, or if using Windows 2000, XP schedule to Compress old files.
Note Win98/WinMe can also use profiles for configuring defrag and scandisk for scheduling.
Note Win2k/WinXP includes a new feature that Compress old files not used the last ? days, by using NTFS compression (blue files). Even if having this option disabled it might still do “Scanning: Compress old files”, which can be slow and make it hang for a long time (It is also activated when doing a defrag). To disable it by force, delete the following registry keys (Make an export first):
[HKEY_LOCAL_MACHINE \SOFTWARE \Microsoft \Windows \CurrentVersion \Explorer \VolumeCaches \Compress old files]
[HKEY_LOCAL_MACHINE \SOFTWARE \Classes \CLSID \{B50F5260-0C21-11D2-AB56-00A0C9082678}]
