The command line option
--selection (and --print-selection, which is a synonym) shows the items that are selected for and excluded from backup. To run this command, first quit SpiderOak ONE if it is running. Don't just minimize the application, shut it down completely by clicking or right clicking on its icon in the notification area, then selecting Quit. Open a terminal or a command prompt window. Then enter the appropriate command at the prompt and press enter:
cmd /c "C:\Program Files\SpiderOakONE\SpiderOakONE.exe" --selection
This will show the items that are selected for and excluded from backup.
By default, --selection will show results for the device you are seated at. This can be changed by adding the option
--device. For example, to view the items that are selected for and excluded from backup on device 12, use
SpiderOakONE --selection --device=12.
