On my server within the domain of our Forums, I have a folder called

cgi-bin

In that folder there are other folders

Members
Modules

and other cgi-files.

I think that these might be from the time we were on ubb.classic.

Am I correct in thinking that?
And am I correct in thinking that they are not used at all by ubbthreads7.x and that I can safely delete them for good?

Thank you for any help!
