Part2: Shrink/Delete Volume to Get Unallocated Space in Windows 7?

Method 1: Shrink - Right click a large volume and shrink partition with Windows 7 Disk Management which would create some unallocated space (Note: Disk Management cannot expand volume with the unallocated space when it's not adjacent.), so the shrinking partition in Disk Management does not work from our test.
Method 2: Delete - Delete volume under Disk Management on Windows 7 if it cannot extend volume in disk management. (Delete the right side volume, for example, if you want to extend c, delete it's right side volume D, or any one that stands besides the c drive)delete partition

This one would work.

Question: Add Nonadjacent Unallocated Space to Windows 7 System Partition

As mentioned above, you have to make sure that the unallocated space is adjacent to the system partition if you want to add it to this partition. You have two choices to add unallocated space to extend C drive on Windows 7.

Method1: Windows 7 disk management delete volume to add the unallocated space C drive

#1 Deleting the c drive right side volume when the unallocated volume is close to it

#2 Right click the system partition and then select the Extend Volume option so that you can add the unallocated space to the selected partition.

Note: Disk Management can only expand volume c when there is contiguous unallocated space on NTFS volume C. It won't work when there is no contiguous right side unallocated space, or when the c drive has FAT32 file system. (3rd party free tool Partition Resizer can help under such circumstances.)

Method2: Free 3rd party software Partition Resizer

This free tool can help move nonadjacent unallocated space to c drive by moving the inbetween drives free without losing data and then you can add unallocated space to c.
