-// These functions convert the input path to an absolute Windows path
-// with "\\?\" prefix, then pass that to _wopen/_wmkdir/_waccess/etc.
-// (declared in <io.h>) respectively. This allows working with files/directories
-// whose paths are longer than MAX_PATH (260 chars).

-// This file is only used on Windows, it's empty on other platforms.
