About groups of database objects
You can organize different types of database objects into a group. For example, you can manage a form with multiple subforms more easily if you create a group that contains the main form, the subforms, and the tables or queries that they are based on. You can also create a group for the forms and reports that you use most often; when you click the icon for that group, both the forms and the reports appear in the Object list in the Database window.
A group consists of shortcuts to the database objects that belong to it; adding an object to a group does not change that object's original location. When you click Objects and then click the icon for a particular object type, any database object of that type appears in the Object list
Deleting a database object shortcut from a group does not delete the object itself. For example, if you delete a form shortcut from your group, and then click Forms
under Objects in the Database window, that form still appears in the list of all forms.
