thank you for your reply, those would work when I am dealing with computer savvy people. many of the people I work with have a limited understanding of computers. I would like a system like http://www.yousendit.com/Share-Large-Files
where I can upload the files to my dedicated server, then send them a link to the file That will allow them to download the file simply by putting in their e-mail address as a password.
I have an utilized FTP with some of my clients, but with others it becomes a problem for them and me because I end up spending far too much time explaining to them how to utilize a particular service.
