Double-click it on the Workspaces tab of the Launchbar.
Tip: You can group file sharing workspaces together by sorting
the workspace list by Type.
If you're navigating for the first time to a file sharing workspace
you received by invitation, you're prompted to select or create a folder
to be synchronized, and to specify
initial download settings (automatic or manual).
Select any file sharing workspace in your Windows
file system, and click the Folder Sync button in your Windows toolbar
to show file sharing workspace options and features.
A synchronization icon is appended to the root folder of the file sharing
workspace in your Windows file system.
Click the Folder Sync button in the Windows toolbar again to display
the standard Windows Explorer File and Folder Tasks panel.
