Description

Note: On Windows, ExtractFileDrive returns a string containing the drive portion of a fully qualified path name for the file passed in the FileName. For file names with drive letters, the result is in the form "'<drive>'". For file names with a UNC path the result is in the form "'\\<servername>\<sharename>'". If the given path contains neither style of path prefix, the result is an empty string.

Note: On Linux, ExtractFileDrive always returns a zero-length string.
