Where can I get the file formats for the built in Apps?
There are couple of ways to find this information. If you have Metrowerks software’s CodeWarrior the source for all the apps is included, and you can read the record structure from the header files. This gives you the structure of the records as far as a Pilot App is concerned. If you want the binary format for the files so you can modify them directly you can find it at Nico Seessle’s home page. Note that if you want to read/write the files directly, you have to interact with Pilot Desktop to keep from arguing with it about who gets to write the file (otherwise it wins). See Interacting with Pilot Desktop to see how to do this.
