videos are currently stored in internal storage, so :
internal_data/t_tut_data/lessons/0/52-3b843433711c03c8ff47a6e29309d0d0.mp4
Similarly other attachments to a tutorial are stored there...
Because they are private (and you dont want someone downloading them)
I havent a plan to allow users to set a path, we're you thinking for an external resource, or to point to existing files/videos?
It's not something I had planed, and I'm not sure how widely used that would be (I'm trying to do things that everyone wants, general solutions 1st)
