How to share files
Sitemagic CMS has an extension called 
Downloads. You can 
enable Downloads from Settings. When this extension is enabled, a folder called 
downloads will become visible under 
Content > Files.
 
Upload any file you want to share on your website to the downloads folder. Then, to create a link to one of these files, open a page for editing, and use the link dialog to select the file from the Link List menu as shown below.
You can even keep track of how many times each file has been downloaded by browsing to Admin > Downloads. This will give you a view similar to the one below.
