Effect of file operations on its own and its parent directory's modification times

\		 File added		 File modified		 File renamed		 File deleted		 File		Y		Y		 N		 N/A		 Parent directory		 Y		 N		 Y		 Y 
 (Y = mtime updated, N = mtime not updated) 
 This has been tested under Windows XP and Solaris. I think the effect is the same on other OS but I have not tried.
