How to format unallocated space on C: (internal) Drive in Win10. Bit reluctant
You could use Windows Disk Management tool.
Open Disk Management through the Run window by pressing the Windows key + R at the same time, then enter ‘diskmgmt.msc’ and click ‘OK’. Once Disk Management has loaded, right click on the C drive, and select the Extend Volume option to extend the C drive with the unallocated space.
If the unallocated space is not adjacent to the C drive, or the unallocated space is not on the right hand side, you will delete the partition(s) between the to-be-extended partition and the unallocated space. In Windows 10 Disk Management, right-click the partition that you need to delete and choose “Delete Volume”. Then, right-click the to-be-extended partition and you’ll find “Extend Volume” is enabled. What you should know is that all data on the deleted partition will be lost.
Hope above information can help you.
