Hi Folks! Only recently discovered via Fred Langa that the Disk Cleanup manager in Programs > Accessories > System is much more powerful than I'd previously thought. The trick is to start the program with the magic words "sageset" and "sagerun". These two articles http://goo.gl/0PWX9 http://goo.gl/2gS1a give a gentle introduction. And here's Microsoft's documentation: http://goo.gl/rA9wG Note that these articles are valid for Windows XP and later. When you run cleanmgr with the sageset option, you'll find yourself in a list of 13 items. Use the up and down arrows to navigate and spacebar to set an option. Items 2, 3, 7 and 12 have additional options. Press Tab to access them and Shift+Tab to return to the list. And be careful! Once the files have been erased, they've been erased, good luck, John
