I would appreciate any help with this task. The hard drive in question is split into 3 partitions, with C having a size of 59GB. The problem is, it is full, but it should not be, because iTunes stores all data on D, all larger programs, except for Office 2007 and Steam are installed on D, and all other music/videos are on E. I have already run the inbuilt windows cleaner, removing temporary files/system restores, etc as well as run Ccleaner and uninstalled larger programs, but to no avail. The thing is, my only documents on C are .doc's and don't take up much space, so I am not sure what to move and the few programs installed shouldn't take up much space either. I have a feeling that iTunes is behind this, as every time I connect an iPad, the C drive fills up every space I had previously freed up. One example: After removing XP mode, which takes up 1.1 GB, there is still only 300MB free, it had 700MB free, before I removed it. At one point there were even 5GB free, but when iTunes runs, it goes havoc The thing is, I don't really care how much or little space is free, but I did reset my iPad yesterday and now iTunes won't restore due to a lack of free memory. Is there something along the lines of an emergency cleaning button?
