Vista - Help with Disk Cleanup

Hello there,
I've been meaning to clean up drive "C" on my computer and i've removed everything i don't use and still require more space.
I was wondering if I'd encounter any trouble if i wiped out the 12gb part in the attached screenshot. I'm not good with computers & have no idea if its safe or not.


Also, if i can't remove these files, is it possible to add unused space from another partition on the same hard-drive to the partition where my OS is installed?

Thanks in advance

Hi RambleOn,

I would not delete that one. It is suppose to be safe, but everyone that did it had to do a reinstall afterwards to fix Vista. I would recommend that you do a Repair install ro fix this problem, then run Disk Cleanup to get rid of what you want.

This will show you how to delete one partition to use it to extend another one. Be sure to read the NOTE and WARNING at the top.
