Rainbow is an app that allows users of Android to directly transfer files between Cloud Storage services. However, this app is still in its developmental process, so there are chances of bugs which isnít a big issue and if you donít find your Cloud Service on it, go to XDA Forums and vote your Cloud Service in the poll. Now, letís see how we can install and use this app.
How to Install and Use Rainbow:
Download and Install Rainbow from Google Play Store.
Once you have installed it, open it.
Make sure that you have a working Wi-fi connection.
You will see a list of Cloud Services that are available, tap on the one you want.
Youíll be promoted to the Log-in screen, Log-in using your account.
Accept the administrative permissions to successfully connect to the service.
After you have configured all the accounts you wish to manage using this app, tap the Data Transfer tab
Youíll see the list of accounts that you have configured, including the Android device.
Tap on the one from where you want to transfer the data, you wonít be able to see any thumbnails.
Once you tap a file, a pop-up containing two options, Delete and Copy, will emerge.
Tap copy to copy the item to clipboard or delete it if you want.
Now all that is left is to open the other Service and paste the copied data there.
It will take a little time, so please be patient.
