In order to conserve the limited internal data storage
on my Galaxy 10.1 Tablet for navigation
and other free/reasonable apps,I have bought Samsung's USB inteface plus a tiny,dongle size 8 GB pendrive from Multilaser with a 5 year GUARANTEE!!
I have changed the path to charts/routes etc. in my OruxMaps pointing to the pendrive.
Navigator requires presently a fixed internal path so I have created an identical path pointing to the pendrive. Finally,in both cases I have duplicated all relevant files on the pendrive,and deleted all un-necessary files from the internal directories.
In this way,I have access to all my OruxMaps data files from the pendrive and only download the charts
etc for MarineNavigator I will use for each individual cruise
and delete them from the internal directory after use. I have spoken to the creator of MarineNavigator who promises changes in future version to enable path changes.
finally are ported to Android,I will store ALL charts
and other space hungry data on the pendrive.
The bluetooth file transfer also works very well between my laptop
as well as my Galaxy SII smartphone.
