To start up Start using CrosExplorer, you'll need to sign into an account on one of the supported cloud storage providers.
Please note, if you choose the Single-Sign on method for Box Cloud, you can only mount one account from that provider.
Once the file is visible in the CrosExplorer pop-up window, you're free to use your files in the ChromeOS Files app.
To keep costs down and remain a one-time purchase application, we stopped paying the hundreds of dollars required every year to qualify for CASA. This was done in the past, and the Google Drive functionality remains unchanged.
Today, the application data still only goes between you and google being that this is a Chrome Extension.
Your files still never touch any server or cloud storage besides google's own.
