A computer program's run-time inputs and outputs are dynamically, non-intrusively, and executable-independently determined by wrapping a "Wrapper" around the computer program. The "Wrapper" turns on system traces (102), executes the computer program (104), and turns off the system traces (106). It then reads and evaluates the traces (108), identifying process and file information corresponding to the recent execution of the computer program (104). This process and file information is collected and written to a Run History data base (310).
