yes it is a old ini.file
Belive me, i have spend many of times try to understand this matter, but no chance.If you want to replicate it and make another skin, you can try that by learning the Ways of Rainmeter
A good friend has try to explain me this to understand, but i don´t understand this, it is to complicated for me like Mathematik.
There are enough Weather skin, but not with the same weather icons, and that is the reason, why i would like to use this old Skin.
And start a new weather ini.file with the old weather icons, that is out of my imagination, because i don´t understand this matter.
i hope you understand, it is not easy for me, and who has time to slove this problem, most of us are busy, and they have private life too.
