Adding a folder in the root directory

I've a coverted a pdf to flip-book to embed it on squarespace website. But it doesn't have any link to paste. Instead, I have to move the whole folder in the root directory. For example, the folder name which contains code is "Test". I have to move the folder to the root directory so that if I use the URL www.***.squarespace/Test.com , it will direct me to that site. 

PLEASE HELP !! ANY POSSIBLE SOLUTION FOR THIS ? 

Squarespace is not suitable for this. I recommend you choose an alternative flip book style solution with Squarespace that can be embedded.
