Cannot delete forms directory

How do you delete a directory called "Forms" in a SharePoint 2007 document library? This is not the reserved, hidden "Forms" directory where the templates go. I know that shouldn't be deleted. This is a user-added directory called "Forms" a few levels below the document library root, e.g. /sitename/documentlibrary/subject1/subject2/forms/

In the web interface, the site throws an error:

In SharePoint designer, it gives this error:

I can't figure out how to delete these custom "Forms" directories. Google has been no help. If you have a solution, please let me know. I will post any solutions I find.

Should we really not ever have any document library folders called "Forms"?

Vista law soot

Check out this cute story about the lawsuit over low-end Vista.

I generally agree. Microsoft screwed themselves with these numerous versions. While I, as a technically minded individual, can understand the differences in the varying versions, most people won't. My favorite quote:

"Because we here at CG are Microsoft shills, it's hard for us to badmouth the mother ship but this was our complaint from the start. All these ridiculous versions--Basic, Ultimate, Penultimate, Super Duper--just frustrate the bored and litigious. Make everything Ultimate, make everyone buy a new PC, and suck up the loss in low-end sales."

I am really buying a Mac as my next computer. Really. Or maybe I will go with Linux. Or a pad of paper. I'm a little confused in the head.
