Question about adding sub folder directories

OK, I have owned my smart ftp program for almost two years now and I LOVE it!! 8) I have a question.

Folders (left side in FTP)

shows all folders

Files (Right side in FTP)

shows all uploaded files

When you add a sub folder, you add it in the "Folders" section that I have listed above, right? I did that then when I clicked on the new folder that I added, the only thing it showed was "Parent Folder". I then uploaded a page and a file to that folder and it showed it listed under "Parent Folder" in the files section. But when I went to my site, it did not show that page or that file. It said "page cannot be displayed." So, does this mean I am not doing it right or do I have to change the link for that page and file to show up on my site. If I have to change my link, what do I change it to?
A current link I have now is : http://legacyandjustbreathe.net/clip1.html
(this link is just an example - this page does not exist)
do I have to change that for any page or file that I add in a sub folder to a different link? Please help.
Hope it's not too confusing! LOL!
Have a great day!
