I am trying to delete "Games" folder. Folder size is huge. But it's not deleting. Even not showing a message.
If I try to delete using cmd. But it shows another error.

What should I do now?

Per the answers in this question, the Windows API simply cannot handle certain odd characters. The accepted answer offers that you can try chkdsk. The other option is to boot to a Linux LiveCD that can handle the names, access the hard drive from the LiveCD, and rename them.
Edit: Misread your screenshot. Removed my reference to your C:\ drive.
Here are a few things that you can try:
chkdsk D: /fI haven't personally run into this issue before, but hopefully one of these things will help you clear these files off of your drive.
