How to merge non adjacent partitions in Windows 7:

  1. Right click E: drive and select "Delete Volume", then its space will be changed to Unallocated, remember to transfer files before deleting.
  2. Right click D: drive and select "Resize/Move Volume", drag the middle towards right, then Unallocated space will be moved behind C drive.
  3. Right click C: drive and select "Resize/Move Volume" again, drag right border towards right to combine this Unallocated space.

Resize partitions instead of merging

No matter you merge Windows 7 partitions with Disk Management or third party software, you'll lose one of the partitions. As I said above, if you installed programs into D drive, you can't merge partition D to C.

By shrinking partition, only part of free space will be converted to Unallocated and all files keep intact. Unallocated space can be merged into other partitions no matter they are contiguous or not. By this method, you won't lose partition, Operating System, programs and anything else keeps the same with before.
