Quick Fixed: Extend Volume Is Disabled in Windows 11, 10, 8, 7 for C Drive
Extend Volume is disabled
After using my computer for a period of time, my C drive is full. Thus, I decided to extend it to Disk Management. However, after I right-click my C drive under Disk Management window, all I see is Extend Volume grayed out. Are there any suggestions to fix it?
When will Extend Volume not work properly in Disk Management?
1. Extend Volume only works on NTFS partition or RAW.
2. Extend Volume only works with unallocated space.
3. Extend Volume only works with the right adjacent unallocated space to the target partition.
If your disk doesn't satisfy all 3 prerequisites, the "Extend Volume" is greyed out. To fix it, some users try to shrink D: drive to get the unallocated space. However, you will find the unallocated space you get is right adjacent to D: drive instead of C: drive. That's to say, if there is no unallocated space before you want to extend the C drive, you cannot get any available unallocated space unless you delete the next partition. If you choose to delete D: drive, you must lose your data on it.
