Ctrl + X

Ctrl + V

Boom.  Copy done.
Just select the files you want to move, and drag or CTRL+X/CTRL+V them to where you want them.

Seriously, that's all you have to do to copy from one drive to another.

*edit*
I should say that you should only move files that YOU created, as programs and your Operating System will probably freak out if you move their files around.
*edit*

You might try running disk cleanup (Right click on the drive, click properties, click disk cleanup, check every box, click okay).

Also, if you have SP1, you're happy with it, and you have some basic knowledge of the Windows command prompt try this:
Open a command prompt with Administrator PRIVILEGES (Flag key > type "cmd" > HIT CTRL + SHIFT + Enter)
In the command prompt, type "vsp1cln" and hit Enter.
A prompt should ask you if you really want to delete the files (y/n) if you type "y" you will never get those files back.  They're old pre-SP1 files, so not a big deal.  Might net you a gig or more.

If you're still not happy, go back into disk cleanup and click the "more options" tab.
Under "System Restore and Shadow Copies" click "Clean Up..."
This will delete all but your most recent system restore point and all shadow copies you might have laying around.

Here's another one that might net you space, might not.
Open up a command prompt with admin rights again.
Type "powercfg -h off" and hit enter.
that turned hibernation off.  If you use hibernation, I wouldn't recommend doing this.  However, if you don't, this should free up as MUCH HDD space as you have of RAM.

hope this helps.
