What are the different folders of my domain for?
The different folders that we can see at the web hosting from the FTP access help us to organize our web pages files.
By default, domains registered at MrDomain (On each provider this might be different) point to the /public/ folder from the web space. To see the files from your domain (http://www.yourdomain.com) they must be inside this folder.
If you want to create a new web page in a different path, like "http://www.yourdomain.com/shop/", it will be necessary to create a folder named "shop" inside "/public/" in a way that the files have to be uploaded to the "/public/shop/" folder.
It is also possible to change the folder where the domain points from the "Subdomains" tab, by editing the directory to the folder you want.
