1. Set the storage awareness function of Win 10.

We click the menu button on the desktop, select "Settings", and select the system in the windows Settings interface.

2. Then select "Storage" in the menu on the left, then we open the button of "Storage Awareness", then set it in "Change detailed settings" below, and finally change the path to a non-C drive in "Change the storage location of new content".

PS: Set according to your actual situation.

Method 2: clean the disk of disk C.

1. Open my computer, right-click drive C, select Properties in the menu, and then click Disk Cleanup in the Properties interface.

2. We will find the results soon, but there is not much data to clean up. At this point, we will click "Clean System Files" again. At this point, we will find that the system needs several minutes to process this instruction.

3. Wait for new results. At this time, we found that we could free up more space, and then we clicked OK-delete the file.

4. After that, you need to wait for the system to clean drive C, which will take some time.
