  Be careful with this if you share elements across applications.   I'll give you an example to illustrate:

   Application A                           Application B

   Entity EMP                              Entity PO
   Entity SALARY                           Entity PO ITEMS
                                           Entity EMP (shared from App. A)

   If you export Just Application B, case will "create" a new    application called "01A" with the EMP Entity in it. Your    export file will then contain:

    Application 01A (Frozen) Application B     

     Entity EMP                           Entity PO
                                          Entity PO ITEMS
                                          Entity EMP (shared from App. 01A)


     This can quickly cause a big mess when you bring Application B
     back in and rename it.  Unhooking the shared EMP Entity from
     "01A" and hooking it back up with the EMP Entity from "A"
     can cause some strange things to happen.  I only tried this
     once and ended up reverting to a previous backup.

   I know this is off the original topic, but, hey, it can be    a problem . . .
