web design help

hi

I want to build web site which selling media.
the user could download the content of the site with ftp.
my problem is that I want prevent from the user to download
files that he did not pay for them.
I can I do this??

I thought to build temp dir which will keep the content of the files that the user buy or shortcut to this file ?
is it good way?
or there is another way?

thanks

your wanting to build a complex website, accepting payments and stuff right?

This is going to take some programming, maybe you could even find a free content management system or e-commerce system that would do this for you..or even a cart program... all server side of course.

But if you want to do this you should already know the answer to your question. The fact that you don't says to me that this is too much work for you alone. Sorry.. it's just how I see things on my side with the limited facts given.

Maybe someone here knows of a free or paid program you could use for what you want.
Hopefully, that way you could make this website relatively quickly and easily
