Is there anyway of increasing the system drive (C) size?

I have 1 750gig HD at the moment with 2 partitions on, C being the system and D being used for storage, at the moment i can increase or decease D but not C, even when decreasing D it still will not let me increase the C drive, rapidly running out of room on C and would rather use the spare space from D then get another drive. hope that all makes sence.

Any help much appreciated.

I use EaseUS Partition Master - Home Edition

It's free and it is capable of doing what you require with ease.

Here are some instructions for what you are wanting to do.

Why not junction some of the large directories off?

http://www.rekenwonder.com/linkmagic.htm is an app for doing that, however it can be done manually in windows 7 if you know the commands.

Two new items for my Windows tool repository, thanks
