Extend Partition

This guide will show you how to extend partition without data loss, which can be used to enlarge any partition and fix low disk space issue in Windows.

Step 1. Right-click on the partition you want to extend and select Extend Partition option.

Step 2. Select a partition that contains large amount of free space and click OK.

Step 3. Set partition size you want to move between these two partitions and click Start.

Step 4. DiskGenius lists operations to be executed and things you should be aware. Click Yes to continue.

Step 5. Click Complete button when the partition is extended successfully.

Note:

• If the partition resizing process involves operating system, DiskGenius will prompts to enter DiskGenius WinPE edition to complete the task. If your computer cannot boot to DiskGenius WinPE edition directly, you can create a bootable USB disk to boot computer.
• Please do not access the partition being resized in case of any unexpected issues.
• The resizing process may take long time if there are too many files on the partition. In that case, you can set operations after resizing finishes.
• Partition resizing may fail to complete or even cause data loss due to hard drive or partition errors, bad sectors, sudden power failure or system errors. Thus resizing partition is a risky action to some extent and data backup is necessary.
