Publishing

I am feeling lost once I have published my project in Storyline.  When I finished publishing to ftp, Storyline said it had published to “isolaunch”, which I’ve never heard of.  I found it on my website but when I click on it, it prompts me to download the mobile app even tho I am on a PC.  Thinking to use a different route, I found the folder on my computer, with my title followed by the word “output”.  I want to use FileZilla to put it onto my website as I must not be able to publish directly to my site.  (Had the same problem with Captivate.  I am rural so could be my connection.)  But when I uploaded the folder, it didn’t work.  Am I supposed to use one of the other files files inside instead?
