I have a Samsung Galaxy 3 8.0 Tablet and loaded the Android version of the Ifly GPS a week ago. I asked whether the IFly GPS software would store the data files in my 32 the external SD Card. I was assured that they would be there when loaded. I just checked the data card and the data fileas are all found in the SD card. Although I didn't check to see where the program operation files are located, but I assume they are on the internal memory.
