Can/Should I free up these unused C: partitions?

This is the current layout of my Windows 10 boot drive:



I understand that WIn10 has a required 1/2 gigabyte "Recovery Partition" that it likes to use when required to rebuild the boot partition etc. But somehow, over time, my boot drive has those other 3 partitions, including 776 MB of unallocated space. So my question is: why are those partitions there and can I free them up and make that space usable for something? And if so, what would be the best software to use to do this?

I don't think it matters, but the drive is physically an NVMe Samsung 970 SSD.

Your computer has a 250 GB solid state drive which has an actual capacity of 232.89 GB.
If you add up all 5 numbers, they will equal that amount.
I'm not familiar with NVMe M.2 solid state drives, so I'll pass to someone else here to advise you further.

You could add the 776 mb unallocated to C (or to any of the other partitions if you wanted to).

Minitool Partition Wizard is the tool of choice. A free download.

The others are taking up very little space.......I wouldn't bother with them even if I could.

Great info, thanks. I guess it doesn't matter that the unallocated space is not adjacent to the space used by the C drive.

MiniTool did the trick - thanks.
