So by this you're saying that cygwin-applications cannot handle the
filesystem it is supposed to handle ? 

How come std::filesystem first say "It's a valid file" followed by "It's not
a valid file" ? Is that part of the "circumvention" ?

In the current use case, the path is even returned from
std::filesystem::directory_iterator where it says "Hey, here's a path to a
file I found in the folder you pointed out" followed by "The path I just
gave to you is not a valid path"

It's gonna be tricky to implement applications in that way




Best regards,
Kristian
