Forms collection vs. AllForms collection

[Access_Novice]

The forms collection refers to all forms which are currently open. Then I presume this means that the AllForms collection refers to all forms, opened or closed. Is this correct?

Also, is there any reason why a person might write some code referencing a form that is closed, meaning they would not reference the Forms collection?



When and why would somebody use the AllForms collection when referring to a specific form, instead of using the Forms collection when referencing a specific form?

One example:

Private Sub Form_Current()
With Me
If CurrentProject.AllForms("DataBituminous").IsLoaded Then
    If IsNull(![AGGBULK]) Then ![AGGBULK] = Forms!DataBituminous![610.AGGBULK]
    If IsNull(![EFFECTIVE]) Then ![EFFECTIVE] = Forms!DataBituminous![610.EFFECTIVE]
End If
End With
End Sub
