Once setup is complete, you can add more synced folders or manage existing ones by going to the Cloud Station Server tab. For better flexibility, DS cloud allows you to choose multiple folders on multiple Synology NAS devices at the same time, such as some work-related folders on your Cloud Station Server at work, and others on your personal Cloud Station Server at home.

The status of each synced folder is displayed as follows:

• : The folder is currently being synced.
• : Syncing was unsuccessful because the file is larger than the maximum file size or is not one of the file formats you chose to sync.
• : An error occurred, so the file or folder was not synced. You can get more information by going to the file or folder information page.
• Normal: If the file has no specific status icon, it has been successfully synced and is available on both your mobile device and Cloud Station Server.

To import files from a cloud provider to DS cloud:

The Settings tab displays the following information and options:

• Connection status: This section shows details regarding your account, device name, and IP address or QuickConnect ID of the Synology NAS with which DS cloud is syncing.
• Sync on Wi-Fi only: Enable this option to only sync files when your device is connected to a wireless network (and avoid getting any surprising, nasty bills from your network carrier).
• SSL encryption: enable this option to secure the data transmission both when browsing and syncing files with DS cloud. Encryption requires more bandwidth and may result in slightly slower performances.
• Geofences: iOS apps cannot perform background tasks more than a specific amount of time (3 to 10 minutes). To circumvent this limitation, you can use geofences to define specific areas where DS cloud will sync even when in the background. Tap Geofence > Create to add geofences.

To unlink DS cloud from Cloud Station Server:

On the Settings tab, tap Unlink at the top-right corner of the page.
