# { title }
The GPX file format is an open standard for exchanging GPS data between applications and GPS devices.
It essentially consists of a series of GPS points encoding one or multiple GPS traces, and, optionally, some points of interest.
+These traces can be stored either as tracks or as routes.
GPX files may also contain metadata, of which the **name** and **description** fields are the most useful for users.

In most cases, GPX files contain a single track with a single segment.
However, the hierarchy described above allows for more advanced use cases, such as planning multi-day trips with several variants for each day.
+### Routes
+
+A **route** is a single continuous path made of a sequence of **route points**.
+These are mandatory checkpoints, which correspond to the anchor points of the [routing tool](./toolbar/routing).
+The points in between are only a suggested path connecting the route points.
+Like a track, a route can have a **name**, a **description**, and **appearance properties**.
+
+
+
+Nowadays, most apps and GPS devices work perfectly well with tracks, even for navigation.
+However, some of them only work with routes: in that case, you can [convert](./menu/edit) your tracks to routes, or [create](./menu/file) a route file from the start.

### Points of interest
**Points of interest** (technically called _waypoints_) represent locations of interest to show either on a GPS device or on a digital map.
