The left screen is on the client machine (your PC files and drive letters); the right screen is on the server and are the Web site folders the way you set them up by transferring files. The ASCII mode button and the BINARY MODE BUTTON are gone now in this newer version of WS_FTP Pro. Now just the arrows are used to transfer files back and forth between the server and the client machines. In older versions you had to also select the ASCII mode button for transferring the HTML code and the Binary mode button for transferring an image. PDF files also transferred using the Binary mode button.
 
When you first set up your hosting account, and pay the fee, your hosting company will email you the information needed for setting up the log on for transferring your files by File Transfer Protocol (FTP). Keep your FTP host name, user name and password in a safe place for reference... once you use it a lot, you will memorize the information.
If you are attending a college and need FTP, the college will have their own proprietary tutorial and instructions for your own specific campus. Each student will have their own password and information should not be shared between students.

 

 
This is the logon screen from an older version of WS_FTP Pro. Some of the same information is used in the new versions but the log on screen appearance has modernized. I do not use the tabs of Startup, Advanced, or Firewall when I log on to upload files. The Profile name can be anything you want to use as a casual name for your account. Schools, hosting companies, intranets usually all have their own FTP FAQ somewhere in their Technical Support listings and it is best if you read and know this information before trying to call for Tech. Support for the first time. The information you are calling about may have been in the FTP FAQ and therefore saved you a phone call.
My Web hosting company e-mailed me an information packet when I first signed up so that I had this FTP information at hand when I was ready to use it.
