The issue may be caused by the following:

• You tried to delete a file that was not synced with a cloud or a file that had been synced with a cloud when your mobile device is offline.

• You tried to delete a file.

When the ScanSnap Sync function is set to on, the [Delete from all device] button appears.

To delete files and folders on a cloud service, tap the [Delete from all device] button. If you use the ScanSnap Sync function with multiple devices, tap the [Delete from all device] button to delete files and folders from all devices.

To delete files and folders only in your mobile device, tap the [Delete from this device] button.

To keep files and folders, tap the [Cancel] button.
