# saveFile (deprecated)

{% hint style="danger" %}
**`saveFile()` is considered deprecated**

Support for the `saveFile()` may be dropped in future versions of the JourneyApps Runtime. Please upgrade your app to use [`journey.files.saveFile`](https://docs.journeyapps.com/reference/build/js-ts-apis/journey/journey.files#journey.files.savefile) to ensure that your app remains compatible with the JourneyApps Runtime.

{% hint style="info" %}
**Version and platform compatibility**

`saveFile` was introduced in version **4.25.0** of the JourneyApps Container.

Due to limitations on mobile file systems, this method only works on Desktop platforms.
