Password Protected Directories

I may be going at this completely wrong, so any advice is greatly appreciated.

We have passworded several directories for access from the web. That is working just fine.

However, how on EARTH, using SFTP can we get to JUST THAT directory? I mean, not showing all the other directories on the server, and not by using the main UserID and P/W to the server?

If there is a way, I haven't figured it out. Maybe there's just no way to do this?

Thanking all in advance.

Make an account with limited permission via the server.

You may also want to take a look at the server softwares website,
or help file for complete information on how-to perform this action.
