What is the best disk management tool for windows 11 or windows 10

About the Windows 11 disk management. Windows' built-in disk management tools are intentionally limited to basic operations. The "Extend Volume" feature only works when unallocated space is directly to the right of the target partition, and merging partitions always requires deleting one partition first—which means permanent data loss.

How about the third-party tool if you want to get Windows 11 disk management? They are specifically designed to perform exactly the operations you want without any data loss. If you absolutely must use only Windows native tools, your only path is to:

1. Back up all data from the partition you want to merge

2. Delete that partition using Disk Management

3. Extend your target partition into the unallocated space

4. Restore your backup
