Problem: one of my volumes in Windows 8 runs out of space, so I want to extend it by using system built-in Disk Management. Unfortunately, the function “Extend Volume” of Windows 8 is grayed out though there is unallocated space neighboring to it, and the following picture intuitively shows what I said:
What should I do under this situation?
From the screenshot we find that the most possible reason is that there is no suitable unallocated space, because the function “Extend Volume” works only when there is unallocated space behind and adjacent to target partition while that user’s unallocated space is located before the target partition. At this time, users need the help of third-party partition manager, and excellent partition software can deal with the problem that “Extend Volume” of Windows 8 is grayed out quite well. If users have difficulties in finding excellent partition manager, try using MiniTool Partition Wizard.

After confirming operations, we can see the interface below:
Now, we find the selected partition namely partition I has become 212.66GB from original 138.46GB. At this time, please click “Apply” button to apply all changes to computer. After application, extending volume is finished.
