What are the different download options - Full, Min and File?

First, not all items have multiple download options.

Full

A Full download is ideal for the first time installation of application. It includes everything needed to run the application.

Min

A Min (minimum) download only includes application and setup files. It does not include the files that are generally common to the operating system or that may be installed via another application.

File

This will generally only include the files that have changed as part of an application update, such as the executable and readme.
