I ran out of free space on one of my partitions. Capacity of that partition is 54GB. I selected everything on that partition (including hidden files and folders) and size is 34 GB. I should have 20GB free, no?? All i have is 4 GB. but when i right-click > Properties, it shows me that i have 50 GB of used space. So one of 'em is laying or what? pls help me i want to install PES2010 and it requires 8-9GB of free space.
