i have a technical-problem with a mod here.
I'ved downloaded a mod on this webpage in a .zip-file, and i need to put it now in a mod-folder for Factorio.
My problem is, i couldnt found any mod-folder.
I play Factorio on Steam via Windows 10, 64 bit.
I always ask on Steam-Forum where to find this mod-folder and they said in %appdata%, somewhere under .../user/.
if i search via Windows-Searchtoolbar there is no %appdata% on my SSD.
when i use "search for game-files" in Steam it opens: (D:)\SteamLibrary\steamapps\common\Factorio.
There is a "bin"-folder, a "data"-folder, a "doc-html"-folder and a config-path.cfg
If i open the "data"-folder it shows me two new folders, called "base" and "core" which contains important game-files.
But even there is no mod-folder.
I downloaded the mod here (on the webpage) in a zip-file because i want to modificate the mod itself, for private use only; so a download in the InGame-ModInstaller is not an option.
Pls help me, i got very stucked and pls... explain it for really stupid people like me ...

Thanks
JR
PS: sry for my bad english.
