I run a site for a friend of mine who has a business-site with a shop module where he also provides manuals available for download in PDF format.
Not knowing about this component, he used FTP to upload his PDF files, and then using standard Joomla! weblinks, he made the downloads available to his users.
It took me less than 10 minuttes to install Phoca Download for him, and another 10 minuttes to show him how to use it, which was very easy because it uses familiar terminology; Sections and categories like with Articles.
In less than one hour we converted the old Weblinks to use Phoca Download instead.
I have encouraged him to use the donate button on phoca.cz
