Got it nice tool, it reports my sd card has about 5000+ segments in total that i think is problem as i read only 4000 allowed, will try to cut down the number of segments, but its kind of sucks that they did not make option to disable one map and enable another maybe with reboot, so you it only count segments of active map or some built in file manager would be nice. Device crying for custom firmware...

Thought i can have entire world recorded at once, but guess have to stick with multiple MicroSD cards for this purpose.
