# Navdata Updater

We use a custom-built navdata format that allows us to query and process data independently of any specific application, with very high performance. Unfortunately, Navigraph cannot provide this file format directly through their app.

For this reason, you’ll find **navdata-updater.exe** in the aircraft folder (located in the MSFS **Packages** directory).

If the paths are not detected automatically, click **Add Path** and navigate to your `Community` folder. From there, open `fss-aircraft-e17x`, `fss-aircraft-e19x`, or `fss-aircraft-e19xf`, and then go into the `fss-wasm-data` folder.

For authentication, you can use the modern **consent method** by clicking the corresponding link, or sign in using the classic Navigraph code.
