Always respect copyright. Do not download proprietary map files (e.g., commercial Garmin Topo maps converted without permission).
And the process itself? It is never clean. Projections warp. Attributes drop. Metadata evaporates. Converting a map file is like restoring a fresco: you will lose some original dust, but you might save the face. Tools like QGIS, GDAL, or even custom scripts become time machines. They let a 2008 GPS trace appear on a 2025 smartphone. They let a forgotten forest road escape obsolescence.
Converting .fbl files to open formats like .kml , .gpx , or .geojson is because the format is proprietary and encrypted. Igo Basemap 2012 Fbl - Facebook
