Renaming vault folders that contain files?

I am stumped! I want to rename saome EPDM folders, some I canand others I can't. I am performing the rename as Admin.

An error I get is this.

I have tried getting the latest versions, checking out the files and with the files checked in.

What am I missing?

Thanks for the help.
