    Shue,
    
    The PalmOS does not have a file system as such. It uses "databases" as
    described at:
    
    http://oasis.palm.com/dev/kb/faq/FileFormat/PDB+PRCFormat.cfm
    
    Don't get too excited about the time stamps. You can fabricate a
    database with any date stamp and load it into a device (the modified
    time will be updated but the creation and backup times will remain
    forged).
    
    To become more familiar with the inter workings of the PalmOS, I
    recommend obtaining the Palm Debugger and Emulator from the Palm
    developers site (http://oasis.palm.com/dev/kb/). Also, spend some time
    looking through the Knowledge Base articles. Another useful toolset is
    pilot-link on Unix.
    
    In some instances it many be necessary to access the hardware directly
    to capture all evidence. Extending this thought, has anyone come across
    tools that access the DragonBall processor directly to reach into Flash
    memory beyond what is accessible via the Palm API?
