Saving and Restoring the Settings
Settings include the names and locations of the input and output files, but do not include the stego key. You can save them in a file (with .stpng extension), and later restore them, using the usual Windows open/save dialog box.
Be aware that saving the settings and leaving the settings file on your PC constitutes a security risk, since someone might later load a settings file and discover which data file you hid and where the stego images were located during the operation, although they would not discover your stego key since it is not written to a settings file.
When quitting you are asked whether you wish to save the settings. If so, they will be automatically loaded when the program is next run. If you say 'No' then on the next run the program starts up with no settings.
