I’m running under the blackberry 10 (qnx). There is no root access to 
manually mount filesystems, there is a fuse bundled (but if i’m not mistaken,
i need to be root to use it too?), the internal storage space is limited, so i want
to move tree on external card, but only fat/exfat formatted cards are mounted.

Thanks! I’ll see.

Yes, this is the only way it currently works :) Same settings.
