Every OS needs users to manage the disk resource and protect disks and partitions to keep the system in high performance. Once Windows 11 has been released, its strict hardware requirements force many users to have no choice but to pay more attention to disk management.

Users may need to adjust the capacity of drives, format drives, move programs… Thus, disk management tools emerge as the people’s needs. This article will introduce two disk managements: Windows 11 Disk Management, and better third-party software, and show you how to use them.

Disk Management in Windows 11

Disk Management is a built-in program in the Windows system for all Windows users. Users can run some simple adjustments for their drives but with many limitations. However, it’s necessary to know how to open it and how to use it when it’s available for your needs.

Disk Management allows users to extend volume on any drive but this could be workable only the target drive has an unallocated volume right behind it. Usually, the D drive is on the right of the C drive, so users can create unallocated space from the D drive via deleting all data on the D drive.

Users can also create a new volume, convert to GPT disk, convert to a dynamic disk, shrink or format a partition, change drive letter…

A handy Windows 11 disk management tool

If you’ve used Disk Management in other Windows OS, you will exactly understand how laborious to use it. Many features ask users to delete their data on drives, and lots of ambiguous limits restrict users from flexibly managing their disks and drives.

Step 3. You can take a preview of the operation result before confirming the start. Click "Apply" to execute this operation.


After these 3 steps, your C drive will be extended by the free space from the D drive, and you don’t need to delete anything to manually create an unallocated space right behind the C drive. Users can use the free space on any drive to enlarge other drives.

If there’s unallocated space on your disk, but it’s not on the right behind the drive you wish to extend, you can choose the “Merge Partition” feature.

Method 2. Move installed applications

Some users may install programs on their C drive, which leads the C drive to confront low capacity warnings. AOMEI Partition Assistant can migrate these installed programs to another drive/disk (including external disk). It can move all data files of the program on the disk to ensure the program can boot successfully after the transferring.

Step 1. Launch Partition Assistant, click “All Tools” in the left menu, then select the “App Mover” feature.
