About

This software provides you an ability to mount your Dropbox to Chrome OS (unofficial software).

[Note 2020/01/04] Currently, there is an issue at mounting (the authorization window cannot be opened), and now investigating. As the workaround, the authorization window will be opened after clicking mount button continuously.

Notes:
* This works on only ChromeOS.
* It will unmount automatically when the access token is expired to access Dropbox Core API.
* Multiple accounts can be mounted at the same time.
* The same feature as Project Infinite already supported.
