Background Introduction:

Any kind of physical space on your hard drive not belonging to your partition is considered 'unallocated‘ in disk management. 

Moreover, users cannot see it in Windows File Explorer, which is the leading cause of the hard drive's inability to create unallocated space diskpart. As a result, users can't use the unallocated space just like other general partitions for storing the data.

What’s unallocated space for?

You may use the unallocated space to add it to any other volume or use it to create a new volume especially when after a certain point of time, you may notice that your PC has started running slowly, doesn't respond to your commands appropriately, or the screen becomes black, and the system lags. Your system partition that is generally assigned with the C drive letter is showing a red mark because of insufficient drive space.


When your C drive segments don't have space and run out of unallocated space, you might have a tough time playing out any undertaking on your PC.
