Thank you for your comment. At the gftp web site:
"gFTP is a free multithreaded ftp client for *NIX based machines running X11R6 or later."
1) What is a *NIX based machine?
2) What is X11R6?
3) How do I find out if I have a *NIX based machine? I have a pentium PC.
4) I read that ftp is only for ftp sites. I want to download from web sites such as html files, text files, audio files, and video files that are at sites that have a URL. For example, if I want to download the home page of
www.linuxquestions.org, can I do that with ftp? In my browser, I would go to that URL, select File and select Save.
