Extend Partition in Windows 10 with MiniTool Partition Wizard

  • Contents:


    "Since upgrading to Windows 10, I have had to keep extending the primary partition, now the system partition is up to 250Gb but almost full. I have free capacity on another partition, from which I have been taking spare capacity with any problems so far, but the partition tool Disk Management won't let me take any more. Would appreciate any/all suggestions to extend partition Windows 10".

    Windows 10 System Partition Is Almost Full


    Due to the advantages of Windows 10 including Cortana, hologram technology and more, many of you choose to upgrade to Windows 10 from Windows 7/8.1. After a period of time, more and more data are saved on your system partition, and the data occupy much disk space. Usually Windows will prompt you a specific message "You are running very slow on disk space on local disk (C:). Click here to see if you can free space on this drive". When low disk space warning happens in your PC, the PC runs slowly, then you probably choose to free up some disk space by deleting some unnecessary or old files with Windows Disk Cleanup tool. However, in my opinion, this way can free up a bit of disk space to a certain degree. Therefore, the best way is to extend C drive in Windows 10 if there is some free space on other partitions. But how to achieve this aim? Read on please.

    How to Extend Partition Windows 10


    extend 1 Use Disk Management to Extend Windows 10 Partition

    When referring to increasing partition size, the usual way is to use Windows Disk Management tool. Nevertheless, sometimes when you open this free tool and right click C drive, you will view "Extend Volume" feature is greyed out or disabled in Windows 10, so you can't extend volume.

    can't extend volume

    Do you know the reason? In fact, it is due to the limitation of Disk Management. Here are two points you should pay attention to:

    Attentions:
    1. The unallocated space must be on the same disk, and it must follow the system partition. That is to say, Disk Management only can extend a primary partition with contiguous unallocated space on the right side (logical partition with free space).
    2. The partition you want to extend should be NTFS or RAW file system, otherwise, Disk Management will fail to extend volume.


    In this case, it is because the unallocated space isn't adjacent to C partition. You may ask: is there any tool to do this work? Fortunately, I have one.
