Connect Mode

• Online. Do not synchronize any files to your computer. You can only access this volume when a connection is possible to the server or cloud storage. Files are accessed on demand from the remote when opened and do not take up any local disk space.
• Smart Synchronization. Files opened are made available for later offline access. You can explicitly make files available offline using the context menu.

Mount as read-only volume

Connect
