WinZip Uhm...huh? :)
Kevin, I'm not sure about every single version control application, but most of them have an explorer like interface that will show you all the files that are being stored in the source control database. There might be a toggle for "show all", but you "should" be able to see every file being stored.
My confusion was becuase of your reply....not sure how Winzip is relevant to the question (unless Winzip suddenly sprouted source control capabilities?)
