It is created via the "Offline Repository Handling" mode, that can be entered within the top menu of Device Catalog. All cloud-based Repositories serve as input for selecting the required Device Packages within this mode.
Select the Device Packages, open the context menu and click OFFLINE REPOSITORY. Specify destination folder and file name and start the process. The current status and number of downloaded Device Packages is displayed within the progress dialog.
After creation, the new Offline Repository is stored in the specified local file for further use, e.g. to move it to another machine which has no connection to the cloud-based Repositories.
