With Qlik Sense, you always open apps from the hub. With Qlik Sense Desktop, you can also open apps from a file location.
From the hub
You open an app from the hub by clicking it.
Information noteIf you want to open an app not already in the hub, you first need to import the app using the Qlik Management Console (QMC). You can then open the imported app from the hub.
From outside the hub
With Qlik Sense Desktop, you can open an app not residing in the hub. Navigate to where you keep your app and drag it to the hub.
Information noteThe app file (with extension .qvf) will not be moved to the file directory of the hub. If you want it to be part of your hub content, you need to move the file to the hub file directory.
