Changing a website

I am using Smart FTP 2.0

I have several domains hosting under one plan, but every time I try to upload something to one particular domain, it uploads it to all of them. So every one of my domains looks identical, because I can't figure out how to get it to only upload to one specific domain.

Can anybody help me? I am very new at this. I have been tinkering with this thing for a few hours now and every time I change my index.html it changes all of them, no matter which domain I am working with.

What folder should I be looking in for the specific index.html for each specific domain?

Thanks for your help,

Fred

Hi, for that the best is ask your hosting, the config can change a lot from one to other.
