How to Shrink a Partition (Including C Drive) on Windows 11/10/8/7

Free Disk Space:

If you want to shrink a partition which has a lot of free space, you may use IM-Magic Partition Free, which is able to make a volume smaller without losing a file on the drive for free.

Free space VS Unallocated space

Shrinking a primary partition, you will get unallocated space after the shrinking volume.

Shrinking a logical partition, you will get free space that cannot be added to a volume. You need to delete the free space to convert it unallocated space.

What can you do with the unallocated space?

• Add it to another volume using IM-Magic Partition Resizer
• Move unallocated space or change the location of the unallocated space using IM-Magic Partition Resizer
• Create a volume on the unallocated space
