Well there are DAPs and apps that that do not support folder play. Such as Apple products, and the UAPP app on my Galaxy S4(although the stock player supports folder play, but I have to use UAPP for external DACs which doesn't have folder play).
I just wanted to confirm that folder play works on this like the Sansa products. If it doesn't it will not be very convenient. Folder play is very convenient because you can just load up and pick the folder you like to play instead of creating playlists like the dreaded apple products.
