This works much like your own personal FTP service for your site, whereby you can upload data content for use on your site.
Uploading your files is exactly the same as uploading a picture. You'll notice the interface is very similar to uploading a picture. This done via the uploading button and browsing for the file on your computer.



From here, you can also link the files to your web page, should you wish for visitors to download the file, all you need to do is copy the link onto your webpage.
Right click on the image/file you want and select "view".

A popup window should then appear with a web address on the top, copy this and insert it into the image URL when you add an image next. This is just another way to add images, it is easier to add them via the "Insert Image" option.
For the most part, the file manager is for uploading most data including images, and files. You will have to link them in a similar way.
