Make sure you have logged into your Dropbox account and authorised ( to store and edit diagrams stored there.

  1. Go to and click Open Existing Diagram. If you are already in the diagram editor and using Dropbox to store your diagrams, select File > Open from the menu.
  2. Navigate to the diagram file in your Dropbox folders, select it, then click Choose to open it in the editor.

Note: If you have stored a diagram file outside of the app>drawio folder, will copy it on an automatic save. This is because Dropbox only allows to store data in this specific folder.
