If you don't already have it, download the Dropbox mobile app for easier exporting.
To export a file on the Dropbox mobile app:
- Open the Dropbox mobile app.
- Tap the “⁝” (vertical ellipsis on Android) or “…” (ellipsis on iPhone/iPad) next to the file or folder you’d like to export.
- Tap Share.
- Tap Export file. A list of apps that can open the file will appear. Select the app you'd like to open the file.
Note: Once you export the file to another app, any changes to the file may not be saved back to your Dropbox unless the app specifically integrates with Dropbox.
