Can be deleted from git bash or "del \\.\(path to folder with file)\NUL."
But what is this?

NUL is one of the reserved file names in Windows. More info can be found here https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file. It is not allowed to do any file operation from Windows programs. But it is possible to some file operation with Windows APIs. Hence you can delete or create that NUL file in cygwin or msys2 or git-for-windows.

I already understood, i thought CON is the only reserved name
