I've been always been backing up my system/OS disk with game folders excluded to preserve space. That results in having to wait 3hrs and more to have all the games re-installed. So, I figured I could just create a separate partition for them. I already have all the apps I need installed and I added up their size + Windows folder and it resulted in 30.62GB including pagefile. I figured 32GB partition is a safe bet, eh? One things that will be difficult is the fact that Witcher 2 Full Combat Re-balance mod installs itself into Documents folders and its 5.55GB in size. I am not sure if the folder can be moved somewhere, but I can't have a single game dictate the partition size, especially now that Witcher 3 is coming out in a couple of months! EDIT: Forgot to add the Hiberfil.sys file, which is 13.7GB in size.., which makes total space needed for Windows 8 OS is 43.22GB. Bah, I'll just allocate 50GB to it and that will make Witcher 2 files fit to! What's the best free program to create such disk partitions?
