Description

Returns the drive portion of a file name.

ExtractFileDrive returns a string containing the drive portion of a fully qualified path name for the file passed in the FileName parameter.

For file names with drive letters, the result is in the form '<drive>'.

For file names with a UNC path (Universal Naming Convention), the result is in the form '\\<servername>\<sharedname>'.

If the given path contains neither style of path prefix, the result is an empty string.

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