Can't delete these folders

[BlackMill]

So I just noticed the addition of several "usbdisk"folders to my phone. I don't know how they came to be but I want them gone. The picture is a screen shot within the es file explorer app. When I select all of them and click delete it tells me it can't be deleted. Even when I try just deleting one it doesn't work. I tried doing it from my computer as well but again I'm told I can't. There must be some way to delete them. Any help would be appreciated.
P.S. I am rooted.

If there is an app reading from them you won't be able to delete them...

How can I find if there is an app reading from them?

That I can't answer.... My thought would be to boot into safe mode on the phone and try deleting them then.....

I got the same ones. What are they? Who knows. I just chalk them up to part of the endless mysteries of this phone.

Don't mess with those, unless you never plan to connect device via computer with a USB Cable.
