Alfa Folder Locker is an application that doesn't appear to be available anymore, therefore no support is available. I tried accessing the official website, but a domain error appeared in my browser.
As you can see, it's impossible to rely on support, and no other help files are available. Look in the installation folder of Alfa Folder Locker to see what are the available options (user guides, help files, CHM manuals, etc). You'll have more luck finding the information in that location.
