The free edition of the CM Download Manager plugin for WordPress has a lot of useful track & control features that will help you establish a powerful online file directory and monitor downloads on your site.
Once installation is complete, CM Downloads manager will create an online file directory, similar to the way that the WordPress Plugin Directory does. This is where you’ll be able to add new files and track how popular your files are through the downloads counter feature.
You can also upload new files for download and define where and how you want them to be displayed.
