Hello! Sorry if my question is too trivial and it has already been answered.
I've got a hard disk that has only user data (Music, Documents, Pictures, Videos). It is a Hitachi 500GB (physically available are 465GB, 145GB of which are free space). I'd like to move all those files to the end of the disk, separate the first free 70GB of the disk as a C: partition and leave the rest user files in the existing, but shrinked by 70GB, D: partition. How could this be easily and effectively achieved?
On the C: partition I'd clean install Windows 7.
Here's a photo from the Analysis:

BTW, the latest version of MyDefrag seems to be working fine on Windows 8 Consumer preview. Would it be wise to perform those task under this new OS? Unfortunately I don't have any other OS available right now.
Thank you!
Nickolay
