But There Is A Better Way to Fix "C Drive Gets Red" in Windows 7
Actually, there is a much better solution when drive C is running in low disk space, and it is to enlarge C by taking free space from other partitions, if those partitions have much unused space left.

But how to complete such a kind of increase? Pin hope on Windows built-in Disk Management utility or Diskpart? Of course not, because both programs are unable to enlarge partition by taking free space from other partitions, and they work only when there is contiguous unallocated space or free space on the right side of the drive you want to extend.

Therefore, you need to use third party program if no contiguous unallocated space located behind drive C, and MiniTool Partition Wizard is worth trying, because it is totally free for Windows XP, Windows Vista, Windows 7, Windows 8/8.1, and Windows 10 users. In addition, it will not bring any damage to both data and partition. Now you can try it out by following steps below.

Step 1: download and install MiniTool Partition Wizard Free Edition on your computer.

Step 2: launch the program to get its main window shown below:



Step 3: select drive C and choose "Extend Partition" function from the left side.



Step 4: select a partition or unallocated space to take free space from the drop-down menu of "Take Free Space from", and click "OK".

Tip: partitions and unallocated spaces on other disks will not be shown in the drop-down menu, because basic partitions can’t use space on different disks.

Step 4: click "Apply" button to make this change performed.

Once MiniTool Partition Wizard shows it applied changes successfully, you can open Windows Explorer or Computer to check whether drive C is still running in low disk space.

Does your C drive get red, too? Now, it’s your turn to try our method out.
