Thread: How to edit the partitions in Vista?

I have three partitions on my HDD. C:\ drive contains 40 GB, D:\ drive contains 50 GB (Completely Free), and E:\ drive has 270 GB. Now, as D:\ drive is fully free, I want to remove that partition and add that space to the C:\ drive. So, can anyone tell me the best way to do this is?

Right click on the Computer (My Computer in XP) and select Manage. Then, expand Storage and then click on Disk Management. Then, right click on the D:\ drive and select Delete Volume. Then, right click on C:\ drive and click on Expand Volume. Then, follow the on-screen wizard.
