When you duplicate an app, the duplicate includes all the content that you have reading rights to. For published apps, only published and approved content that is part of the .qvf file will be included in the duplicate.
Do the following:
Open the QMC: https://<QPS server name>/qmc
Select Apps on the QMC start page or from the Start drop-down menu to display the overview.
Select the app that you want to duplicate.Note: When duplicating an app, the folder that stores app related content not included in the .qvf file, such as images, is also duplicated. The path to the folder is %ProgramData%\Qlik\Sense\Repository\AppContent\<App ID>. Each app has its own app content folder, with the app ID as the folder name.
Click More actions in the action bar and select Duplicate in the pop-up menu.
Successfully duplicated app is displayed and a duplicate of the app is added in the Apps overview table.
