Data

Mighty Duck’s data is automatically saved to the hard disk after any command that modifies the data. Manual saving is not required.

Advanced users may choose to update the data directly by editing the data file. However, if the file’s format becomes invalid due to these changes, Mighty Duck will discard all data and start with an empty file upon the next launch. Therefore, it is recommended to back up the file before making any edits.
