Simply find each catalog file in Windows Explorer, right-click for a context menu, and use the Send to>Desktop (Create shortcut) command. Give each shortcut a distinct name, then double-click on the one you want to work with. It will open in the Organizer.
Problem to solve: Currently if we want to switch between catalogs we must use: File->ManageCatalogs->Select the catalog -> Open alternatively we can use Ctrl-Shift-C->Select the Catalog - > Click Open
You only have to keep the shift key pressed when launching the organizer to get the menu to select catalogs. That's useful when the requirement is not for a given user to select its own catalog, but for yourself to switch between several personal catalogs.
