While the underlying NTFS filesystem can handle paths up to ~32,767 characters , many applications and parts of the OS still rely on these older APIs, which are hardcoded to respect the `MAX_PATH` limit .
Starting in Windows 10 , version 1607, MAX_PATH limitations have been removed from many common Win32 file and directory functions. However, your app must opt- in to support the new behavior.
