It primarily adds unallocated space to the adjacent partition. Therefore, if there is no unallocated disk space next to the partition that you want to expand, then this method won’t resolve the C drive disk space. issue.

It is to be noted here that this method is only applicable to the NTFS partition. This method doesn’t support the FAT32 partition and exFAT partition. 

Also, it is essential that the unallocated space is available on the right side of the partition besides being available in the adjoining partition.

Here’s how you can extend C drive disk space in Windows 10 via Disk Management:

• Launch the Disk Management console from the Start menu.
• Then, right-click on the C drive in the Disk Management console to select the ‘Extend Volume’ option.
• Finally, when the Extend Volume Wizard shows up, just click on the ‘Next’ button.
