Compared to the System Importer in the Desktop launcher, you can only import ZIP files.

To open the System Importer, click the Tools button in the upper left part of the Desktop, and then select System Importer from the menu.

Open File dialog in the System Importer

Click the Browse button, and in the Open File dialog that appears, browse to and select the ZIP file that you want to import. The file that you select populates the Input Source field.
In the Available Entries field, expand the folders and select the check boxes for the entries that you want to import in the Include column.
Click on the Import button to start the import process.

The folder containing the files that you imported is added to your list of configurations in the Configuration Navigator.

For further information on the System Importer, see 6.13 System Importer but note that the user documentation is written based on when you are using the Desktop launcher.
