Robocopy created a hidden folder, I cannot delete it.

I created a Ropocopy batch file to copy a directory I am planning on migrating at the end of the week (on Windows Server 2012 R2 Std).

I realized that I actually wanted to put it on a different drive, so I went to delete it, but it does not show up in Windows Explorer.

It DOES however appear if I manually change to it via Command Prompt.

I want to delete it but can't.

I tried using RD, but it tells me the folder is not empty, even though it is.

It's very strange behavior.

Can someone help me figure out how to delete it?
