**Open a file in a new layer.**

The following dialog is displayed:

By default JOSM can open OSM data files, GPX files, NMEA files, GEOJSON files, JSON files, OSN files (Notes), WMS files, session files, JPEG and JPG files.

If you type the name of the file to open and omit the file extension, JOSM tries to guess it and opens the correct file.

Several file compression formats are supported too, including `.zip`, `.gz`, `.bz`, `.bz2` and `.xz`.

There are some [wikitr:/Plugins plugins] which extend the file type list (see e.g. code snippets from [https://github.com/openstreetmap/josm/search?l=java&q=extends+FileImporter&type=Code&utf8=%E2%9C%93 core] and [https://github.com/openstreetmap/josm-plugins/search?l=java&q=class+*+extends+FileImporter&utf8=%E2%9C%93 plugins]).
