# Exporting mappings to an AtlasMap catalog file

After all mappings are defined, save the mappings by exporting them to an AtlasMap `.adm` catalog file:

1. Click the AtlasMap menu and select Export the current mappings and support files into a catalog (.adm)

   .

2. In the Export mappings field, accept the default name or enter a name for the exported `.adm` file. The default name is `atlasmap-mapping.adm`.

3. Click OK.

   The catalog will be saved in your Downloads folder.

4. Note, you can later import the .adm file by using the AtlasMap menu.
