I'm downloading everything interesting from the Corel FTP site right now. BTW, it was hard to find a good and working GUI ftp client for OS/2. I ended up using JFTP, it seems to work. I could have used command line tools such as wget, but I prefer graphical FTP client. And downloading files one by one with Firefox makes no sense in this situation.
I have already forgot the name of the client I used with Warp 3.0 over 20 years ago... There was at least one good FTP client if my memory serves me right.
