How to figure it out the form is Interactive form?

Hello,

Since we are SAP ERP based, in both cases (Interactive or Non-interactive) we have to use the LC designer for to create either Adobe Interactive forms or Non-interactive Adobe forms.

We created few AIFs, and few non-AIFs, well, but as a user pl. let us know how can I figure it out that the form is a AIF or non-AIF?

I tried from FORM -> MENU -> PROPERTIES, also tried MENU -> EDIT but no luck

Thank you
