I think, embedding the ini files into the executable was a good idea: It makes it easier to carry over customizations to a new CCleaner version. But, in my humble opinion, Piriform should explain how exactly to use the different ini files (1+2) and - more importantly - make the embedded ini files available for download (or did I miss something?). This way, especially new user would have something to start with.
Thanks for developing and sharing this great software.
