I've got to say that Filerun is exaclty what I needed, Its fast, low weight and has a very nice interface.
I'm using it for personal use with a raspberry pi 2B, connected to a simple Buffalo Linkstation NAS and while of course it's a limited system, for my setup it goes perfect! I can understand why in better systems it can work very well for business...
Thanks & keep the good work
