Detailed description of the problem:
Due to various reasons, I reinstalled the system (Windows 10) but found that there was a problem when the computer was partitioned. After logging in, there was only one C drive. I don’t know where the remaining unpartitioned memory went. I understand that only 200G is allocated to the C drive)
Solution: (screenshot demonstration is for Windows10 system)
very simple,
Click the win+E key combination to open the file explorer, click [This Computer] and then [Right] click [Manage]
Then find and click [Disk Management], and you will see the unallocated partition space appear on the far right [Right-click] and the words [Add Simple Volume] appear, click.
Click [Next] one by one and look at this interface. You can choose how much memory to allocate the size of this volume, and then continue to click Next to re-allocate your memory. After clicking the interface, you can see [I Disk D appears in My Computer].
OK, it's over here. Thanks
