Another (easy) way is to make the settings file (.PLS) read only and then in Windows assosiate it with PicoLog.exe.
1) Create a settings file and give it a meaningfull name.
2) Make it Read Only in File Properties.
3) Right click the PLS file in File Explorer > Open With > Choose Program > PLW32 and 'tick' "Always use this program to open these files".
Now anyone can start the PicoLog program with the same settings as when the file once was saved if he double clicks on the settings file (PLS file).
Hint: Keep a change log file and the old files in an archive folder. Rename the old files with a serial version number or date.
If you need to alter settings, of course you have to make the file writeable again before starting the program.
