A number of things to be taken into consideration.
FTP is mostly needed when uploading bigger files to a server.
The same thing can be accomplished much easier by using I.E. or Netscape. In both of these cases you need to have the login information. After that you can transfer via drag and drop from windows explorer (or My Computer).
Sending attachments with email is very easy, as long as you don't exceed the size allowed my either the sending or receiving ISP (Often that is around 5 MB but the size limit is moving up).
When sending attachments, especially of executables, or even some video files, some virus checking programs may delete them as being dangerous. In that case creating a zip file will eliminate the problem.
Finally, the first answer was transferred from a source like Wikepedia (boilerplate), without being necessarily pertinent to your question. In fact if you check the answerer's 'home page' you'll note that he is so sloppy, he even misspelled the name of Nietzsche twice, both his first and last name. Not a good source I would think. ;-)
