Random Opener+

Open a random file in a given directory.

To setup your directory just type "randomsetup full_path_to_your_directory", or even better, type only "randomsetup" and your frontmost Finder window's open directory will be selected**

To run just type "random open" in Alfred bar. A random file within the given directory will be open and will not be randomly selected unless every other file has been opened.

Reset and count options also available.
