I'm so lost now. So, in my phone's settings I selected OSM and "moved to SD card". Boom. Done. I open OSM and go to change DATA STORAGE FOLDER. Won't allow me to select ES2. Only ES1 (internal storage) and it has ~2gb. I go to File Commander and see the OSM folder in internal storage. Empty. I got to the OSM folder in the SD. There's all my files. So, OSM is telling me the files are going to the internal. The phone shows the files in the SD.
