	// Jon on the AutoIt forums says "Well SHFileOp is way too unpredictable under 9x. Grrr."
	// So the comments below about some OSes/old versions are probably just referring to 9x,
	// which we don't support anymore.  Testing on Windows 2000 and Windows 10 showed that
	// SHFileOperation can move a directory between two volumes.  However, performing copy
	// then remove ensures nothing is removed if the copy partially fails, so it's kept this
	// way for backward-compatibility, even though it may be inconsistent with local moves.
	// Obsolete comment from Util_MoveDir:
	// If the source and dest are on different volumes then we must copy rather than move
	// as move in this case only works on some OSes.  Copy and delete (poor man's move).

		// FOF_SILENT (which is included in FOF_NO_UI and means "Do not display a progress dialog box")
		// seems to be bugged on some older OSes (such as 2k and XP).  Specifically, it answers "No" to
		// the "confirmmkdir" dialog, which it isn't supposed to suppress, and ignores FOF_NOCONFIRMMKDIR.
		// Creating the directory first works around this.  Win 7 is okay without this; Vista wasn't tested.

	// The wildcard below is kept for backward-compatibility, although as indicated above, the
	// issues alluded to below are probably only on 9x, which is no longer supported.  Adding the
	// wildcard appears to permit copying a directory into itself (perhaps because the directory
	// itself isn't being copied), although we still document the result as "undefined".
