People Also Ask - Windows 10 Resize Partition FAQs

1. Can Partition Magic resize Windows 10 partition?

Not anymore. Partition Magic runs on Microsoft Windows 98, Me, NT, 2000, and XP, but Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008, Windows Server 2012, Windows 8, and Windows 10 are not supported by Norton Partition Magic.

2. What is shrinking a volume?

The shrink operation means the practice of trying to decrease the size of one hard drive partition to create unallocated space which you can use it for many purposes. You can add the unallocated space to the other partition which needs more space or simply create a new partition with a drive letter on the unallocated space.

3. Does shrinking a volume erase data?

As explained, shrinking the volume is to create unallocated space, but it won't affect the existing data. No matter you are using the Disk Management, EaseUS Partition Master, or DiskPart command, basically no data loss will occur. 

4. Cannot shrink partition not enough space

If the disk volume you're trying to shrink contains unmovable files and those unmovable files are happen to be in the middle of the hard disk, you are likely to receive this error.

5. Cannot shrink a volume beyond the point

When you shrink a partition, certain files like the paging file or shadow copy storage area cannot be automatically relocated, so you cannot decrease the allocated space beyond the point where the unmovable files are located.
