In this article, I introduces 3 ways to extend C: drive in Windows PC and Server. As you see, Windows DiskPart command and GUI Disk Management have many limitations, they cannot help you in most conditions. The best choice is 3rd-party partition software.

Windows built-in tools have many limitations, but they are safe if you use correctly. 3rd-party programs are easier without limitations, but NOT every program is safe. All parameters of related disk, volume and files should be modified correctly while resizing and extending. If any software error or hardware issue such as power failure occur during this operation, these parameters may not be updated or modified incorrectly, of course you’ll lose data in this case.

NIUBI Partition Editor est intégré unique 1 seconde technologie de restauration which can ensure 100% system and data intact while re-partitioning. If any software or hardware issue occur, it can automatically roll back the computer/server to the status before resizing. In that case, nothing will be changed or damaged. So it is the first choice to resize and extend Windows partitions.
