[2005] Getting list of files from a folder (FTP) [Urgent :(]

[Atheist]

Hello!
Im making a software for our Counter-Strike Source server.
I'd like to get all map files (.bsp files) from the map folder using the servers ftp adress.

I tried using this code:

Dim folder As New IO.DirectoryInfo(ftpAdress & "/srcds_l/cstrike/maps/")
        Dim files As IO.FileInfo() = folder.GetFiles("*.bsp")

But it gives me the error "The given path's format is not supported."

So what should I do? Any suggestions?

Thanks in advance.
