I am checking a Visual Studio project and when looking in its solution explorer I found an icon which I don't know what means.
I talk about the icon of the logs folder. Why is it like that, what is the purpose?
The folder is not part of the project, thats why its "grayed" out. The folder exists but not included in .csproj-file, same can be seen with "bin" and "obj" -folders. If you don't want to see these you can unselect "Show All Files" from Solution Explorer:
