My computer C drive used to be more than 40G, why is it now more than 20G

Is the virus hidden? Try reinstalling the system! Let's see if the underlying formatting can solve it.

Hello, it is normal for the C disk of the computer to occupy 40G, because the C disk is a system disk, which will naturally occupy memory.

But it's full.

In this case, is it not that the computer gave you the wrong score of the split.

It is recommended that you contact the after-sales service to help you re-divide the plate, if the other plate is large enough.

I don't know, can I divide the game myself.

Yes, but you need to know how much memory it is, and if you don't have enough system for a new computer, it's recommended that you replace it.

I don't have anything in the de disk, there is a lot of space, but the things in the c disk can't be deleted, and it won't be transferred, can you teach me how to divide the disk.

Refer to it. Let's see if we can split it.

If you can't operate, you need to contact after-sales.

Although all the files in the C drive of your computer add up to less than 60 G, but in the end, your C drive shows 140 G, and only 20 G remains, which means that there are still many hidden files that are not visible.
