## Native SUMO Files

To ease the usage of the supplied files, all of which are within a
XML-derivate, we use a naming convention for the file extensions to
allow a distinction between the contents at first sight. The list of
used extensions is shown below. We of course highly encourage you to use
this pattern.

- Configuration files (always the first four letters of the
corresponding executable with "cfg" appended)
  - **\*.sumocfg** (formerly .sumo.cfg): Configuration file for
    [SUMO](../SUMO.md) and [SUMO-GUI](../SUMO-GUI.md)
