my application uses a proprietary file format for storing and retreiving settings/preferences data. where is the appropriate place to store these types of files, and how can these system folders be found using carbon? i've found some info on FSFindFolder, for accessing system folders, but not sure which folder i would need. kPreferencesFolderType might be it, but all i see in that directory is plist files.. also, in windows, i use the registry to store a copy of the serial number of the app for the users convenience, if they even need it or forgot to write it down. what is the mac equivelent place for storing non-sensitive data out of harms way, and like above, how is it stored/accessed in carbon?
