It seems that when you install a new TCMD version (like TCMD12 beta) side-by-side with an older version and also use the default location (APPDATA\Jpsoft) for TCMD configuration data (inifile etc.) all versions will share the same configuration data files. Not quite ideal in my view, the new version might contain new settings which will not work in the old version for instance. You might also want to keep the settings in the new version separate for experimentation and such. What would be the simplest way to use a new fresh set of configuration files for the newest version?
