[[JOSMImage(session,middle,48,link=,middle,margin-right=20)]]  Keyboard shortcut: **`Ctrl+Alt+Shift+S` ([wikitr:/Help/ExpertMode expert mode] only)**

**Saves the JOSM session (i.e. the currently present [wikitr:/Help/Dialog/LayerList Layers]) to a file.**

This is useful e.g. to save your work for later continue, to transfer your work to another PC or for bug reporting. Some layer types can't be saved to a session, e.g. validator layers.

[[Image(Save_Session.png,link=)]]

The checkbox `Save all local files to disk` below the layers allows to save all local files referenced but not included in the session file.

If no "real" data is included the file extension will be `.jos` while with data the session file is automatically compressed as zip file and the extension is `.joz`.

Life hack: If you want to start JOSM with a predefined selection of [wikitr:/Help/Menu/Imagery imageries], add them, save them as session an load that session at your next JOSM start. This way you don't have to manually re-add all imageries individually.
