About the eReader tab in the Kobo Desktop
If you use the Kobo Desktop to set up and manage a Kobo eReader, you'll see an eReader tab in the application. This tab is only available when your eReader is connected to your computer.
The eReader tab shows you how much space you have left on your eReader, which Kobo account the eReader is logged in to, and what firmware version is installed on the eReader. You can also use the eReader tab to eject your eReader before unplugging it.
