"Cleanmgr" is a disk-cleanup manager included in all Windows from Win98 onward. It doesn’t do a lot in Win98, but has gained power in succeeding releases. In Win2K and XP, it’s actually a decent little tool that has the potential to clean quite a bit from your system, and can even automatically compress little-used files to make them occupy less disk space. Oddly, simply running Cleanmgr does NOT normally give you access to its full power: Instead, you need to modify it a bit.
We’ll get to the mods in a moment, but if you want more info on CleanMgr, click one of these links:
Now, to the mods:
For our purposes, we only need to focus on one pair of Cleanmgr commands: SAGESET and SAGERUN. These commands are designed to allow the Windows "System Agent" to automate the running of Cleanmgr, but we can co-opt it for our purposes.
Click on Start, Run then type
in the Run box, and hit Enter. The Disk Cleanup Tool will run in a special mode that offers you an expanded selection of cleanup choices. Most importantly, it will remember whatever choices you make now, and re-use those same choices when you use a matching "sagerun" command later on.
For now, step through all the choices that the Disk Cleanup Tool offered you, and make whatever choices you wish. Note that some of the offered items may have additional options or advanced settings that become visible when you click or check the item.
I generally select everything that’s offered— I’m looking for maximum cleaning, so I just check everything. But you can select any, all, or none of the offered choices: It’s up to you.
And don’t worry. If you want to change your mind later, you can. Just re-run the command "cleanmgr /sageset:99" and make a new set of choices.
