I am getting notices that my c drive is full and out of space than it offers a clean up window and when I click yes it goes through the motion but does nothing at all to clean up the hard drive. Help please!

remove as much stuff as you can put what ever you can on to discs and delete anything you dont need. also defrag every week and if you can add a bigger drive as a slave and move all your "stuff" to the slave drive. When you reach a certain level of no space the system will become unstable

Remove installed programs via CONTROL PANEL--ADD/REMOVE PROGRAMS; don't just delete them to the recycle bin.

The default setting for IE is 20 days...that means every single site you visited over the past 3 weeks is stored on your HDD. Change the setting to zero & change the amount of disk space used for temporary internet files to 50MB. Then download a program called CCleaner-Slim & use it regularly. http://www.ccleaner.com/download/bu...

I have a friend in Moscow Russia. And about every 2-3 years he sends me an Autocad drawing via attachment. Last one had some sort of bug in it. It would take everything found on hard drive and make up a duplicate copy, and thus used up near all of the remaining area on the drive. If I did a DEFRAG, I could watch it filling up all but maybe one K of space. If I did a SCANDISK (and NO defrag) it would then clear up the space. If I accessed a file and made changes, it would erase the duplicate, and I would then get that little bit of space back, until a Defrag came along, then it got filled up again. So, stopped using DEFRAG a few months ago. Wm.
