Hello to everybody,

I have bought an new Galaxy-S4 with android 4.4
and I have installed locus-free.
Because I like to use this app in offline-mode when I am  abroad,
therefore I have copied osm-maps via the internet on the external sd-card in my new galaxy-S4
But when I like to work with the osm-maps,
in locus-free I can open the folder from the external sd-card
but locus-free doesn't get access to the files in this folder.
That means I can't work with osm-maps.
How can I manage that ?
Thank's to everybody for any information and help

Hans
