# Dropbox synchronisation When syncing with Dropbox, Joplin creates a sub-directory in Dropbox, in `/Apps/Joplin` and reads/writes the notes and notebooks in it. The application does not have access to anything outside this directory. In the **desktop application** or **mobile application**, select "Dropbox" as the synchronisation target in the [Configuration screen](https://github.com/laurent22/joplin/blob/dev/readme/apps/config_screen.md) (it is selected by default). Then, to initiate the synchronisation process, click on the "Synchronise" button in the sidebar and follow the instructions. In the **terminal application**, to initiate the synchronisation process, type `:sync`. You will be asked to follow a link to authorise the application.
