FTP stands for File Transfer Protocol. FTP is a way of transferring files from one computer to another, and is commonly used to upload webpages to your website.
Below I list a few FTP programs that have been around for years. While I haven’t tried all of them (I don’t have a MAC), most of them are easy to use, even for beginners.
The thing to remember when you are FTPing to another server, is all you’re doing is navigating around on another computer (with restrictions, of course).
Most programs allow you to change the view, so by all means, change the view to one you’re most comfortable with. All the programs I’ve seen have had a “Windows Explorer” type view available.
