The back up files should contain a clear way to link all data back together.
It is CRAZY that the back up files DO NOT include linking data or Headers for the data. So basically, if someone decides to leave DSP, they can take their data (if they know where to find it) but with no way to join the Student file to the parent file or the Classes file. This is unacceptable as customers can take their data, but not be able to use it else where.
Extremely disappointing.. I loved DSP until I found this out!!
