Use POIFSLister to work out if they have a single POIFS/OLE2 stream or 
multiple. If loads, assume it's like Outlook (HSMF), use POIFSDump to look 
at the parts. If one, use POIFSViewer and docs and try to work out if it's 
streams of records (eg HSSF), nested records (HSLF, DDF), or streams 

Once you know that, try to do something to do a basic processing of the 
file structure. Then add some .dev. tools to print the structure (look at 
visio, outlook etc for an idea of how we've done that). Use your own dev 
tool to play with the structure more. Finally, flesh out the 
implementation to cover all the key bits, and write lots of unit tests!
