I am working on a SDI application. My CDocument derived class holds a linked list of pointers to CObject derived objects which contains other linked lists of CObject derived objects. The first linked list contains data that almost never changes. The other linked lists are much more variable.
Is it possible to serialize this document data into two parts for an SDI application. Lets say the more static data in a file with extension .ext1 and the more variable data in a file with extension .ext2. Is this good programming design and if it is, how presisely could this be achieved ?
