.OSF File Extension

OsmAnd is an open-source app based on OpenStreetMap (OSM) that allows you to navigate and plan routes offline. It includes various features, including map-viewing, GPS navigation, and route planning and recording tools.

NOTE: You can create OSF files by compressing your plugin, backup, or map as a .ZIP file, then renaming the file extension from .zip to .osf .

To open a .osf file, you need compatible software that supports this file format.
