7.4.31. FILESPEC

Returns a selected element of filespec, given file specification, identified by one of the following option strings. Only the capitalized option letter is needed; all characters following it are ignored.

Drive: On Windows, returns the drive letter of the given filespec. On Unix-like systems, returns a null string ("").
Path: Returns the directory path of the given filespec.
Location: Returns the full location portion of the given filespec. On Windows, this will include both the Drive and Path information. On other platforms, this returns the same result as the Path option.

If filespec does not contain the requested information, FILESPEC returns a null string ("").
