Hi, people.

After having Vista installed just for a few tests for a couple months, I finally decided to definitively switch to Vista full-time.

When I first installed it in my new notebook (which came with XP Pro), I made a 20 GB partition out of my 200 GB to install it, naively assuming I would be able to easily extend it later if needed.

Now my HD is partitioned like:
C - 178 GB
V - 22 GB

Of course, as I'm now installing everything else in Vista, the 22 GB is not enough. I already moved most User folders to C: (this is something easier to do in Vista), except AppData which can't be relocated. The main problem is in the Windows folder itself, taking 10+ GB that I can't reduce in any way.

I tried to shrink the C partition (to be able to expand V later) to no avail. I tried with Vista's disk management, with Diskpart and with Partition Magic. In all cases I don't have an option, or Diskpart tells me that the maximum I can shrink C is 800 Kb. Of course I have more than 60 GB free in C.

I tried defragmenting with PerfectDisk (several times) to see if there is something in the disk which is blocking me, but nothing changed.

As you can see, I'm not good at partitioning. Is there any way in which I can chop some 30 GB from C and add them to V?

Thanks in advance!
