My hard drive used to have 2 gigs of free space (C drive), and no idea why but it is now full. I have tried clean disk, removing things using jgoodies disk report etc. but have no idea where that space went, it could have been system updates?

Anyhow, on the same drive, but different partition I have gigs of space (drives D and E).

Is there a free utility to reblance the free space over to the C drive?

Yes, Easeus Partition Manager. Get the free version:

Can I free up space from the other partitions without deleting them? –  user27449 Jul 10 '11 at 3:10
    
@user27449 Yes, that is the point of that software: You can resize your partitions; take space away from one, and give it to the other without losing data. That said, although I have never had this type of software fail in 17 years, you should make sure that any important files are backed up. The risk is very minimal, but does technically exist. –  KCotreau Jul 10 '11 at 3:16
    
so I resized drive D by removing about 7 GIGS, and now it shows up as unallocated space. How do I move that to drive C? –  user27449 Jul 10 '11 at 3:21
    
Resize C into that unallocated space. –  KCotreau Jul 10 '11 at 3:22

Care to explain (in your answer) what he's supposed to do with it? –  Ivo Flipse Jul 10 '11 at 6:51

My answer on the question My windows directory is huge would also help you with your question.

Run WinDirStat and see if you can find any unusually large files. The program displays all of your files graphically:

WinDirStat

Sometimes you can find a large corrupted file that is entirely useless.

You can do this with Windows 7 Disk Management. Look at the example picture (Disk 0) on this web site

  1. Assuming you have 3 partitions, C, D, E, move everything off of D and onto E.
  2. Delete the D partition (which will destroy all data on it
  3. Right click on the C: drive and choose Extend. You may be asked if it is OK to change the drive type to Dynamic -- this will be OK.
  4. Your C: drive will now be the size of the original C: plus the size of the former D: drive.

Nothing personal, but that is like doing surgery to pop a zit. That is 100X harder than using true partioning software. –  KCotreau Jul 10 '11 at 3:19
    
My D drive has programs installed, I can't just move it. –  user27449 Jul 10 '11 at 3:20

If you can backup the contents of the D drive or are prepared for the contents to be deleted you can use the built-in Windows 7 Disk Management tool.

How to resize C drive using Disk Management:

  1. Open the Windows Start Menu and right-click on ‘Computer’
  2. Select ‘Manage’
  3. From the left hand menu, select ‘Disk Management’
  4. Right-click on the ‘D’ partition and select ‘Delete volume’
  5. Select ‘Yes’
  6. Right-click on the ‘C’ partition and select ‘Extend Volume’
  7. Select ‘Next’ ‘Next’ then ‘Finished’
  8. The C drive is now extended to use the space the D drive did use.
