Hi

    You can but to do it natively the free unallocated space must be adjacent which may require backup E:\, delete E:\ partition, extend C:\, recreate E:\ partition, restore files to E:. There are third party tools that can do this without the adjacent space requirement.

    Hi @Talha ,

    Unfortunately the Windows Disk Management is fairly limited when it comes to extending unallocated space, for you to be able to extend your C-drive, you would need to have the "unallocated" space straight after the C-drive, that is before the E-Drive as shown here:

    To be able to use your unallocated space you would be best off by using any third-party disk management tools to extend your C-drive, use your favourite search engine and you will find many, both paid and free software.

    hi @Talha ,

    your Disk 0 is a Basic disk. This is the reason why it's not possible to extend the logical drive C: using the unallocated space:

    For Basic volumes, the unallocated space for the extension must be the next contiguous space on the same disk.

    Please refer here: https://learn.microsoft.com/en-US/troubleshoot/windows-server/backup-and-storage/extend-data-volume

    You could give it a try to convert Disk 0 from Basic to Dynamic:
    https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/cc731274(v=ws.11)?redirectedfrom=MSDN

    I strongly recommend backing up all data on Disk 0 before performing any conversion or other disk operations!
