Windows 10 Disk Management can't resize SSD partition [Fixed]

I wanna resize my SSD partition on Windows 10, but the built-in Disk Management tool won’t allow me to do so, the Extend Volume option is grayed out, Do I have alternative programs?

Actually, the Windows disk utilities (Disk Management and diskpart cmd prompt) require continuous unallocated space to the target partition with NTFS file system, you can check if the drive you’re about to extend is NTFS or not, does it have unallocated space followed?

We can delete partition next to the drive to make space unallocated again, but there’s no need to perform such operation, since we have better alternatives

  • A: Macrorit Partition Expert
  • B: Macrorit Partition Extender

Both of them are portable programs, the portable package is around 11M, packed with both 32bit and 64bit edition

Step 1: Create unallocated space

1. Click on a large partition, or a partition with much free space, in this screenshot it’s E Drive, it’s next to C Drive, but feel free to use any partition, even a partition far from C Drive, we can move it without data loss. Then click the function Resize/Move Volume

Step 1: Click on the target partition

Click on the target drive directly (we’ll extend E Drive in this example) and click the giant button NEXT
