The  directory  “AGPS-Tracker“, that contains both gpx and photos will not be destroyed even if you uninstall AGPS-Tracker or AGPS-TrackerOm. This directory is accessible by any File Manager App. Photos are stored in a subdirectory with name “AgpsTrackerPhoto“. The name “AGPS-Tracker” was predefined in older versions of the App, for new versions it is only a suggestion. The user may also have more than one directory for his tracks and photos.
