===========
Windoze management, in their infinite Wisdom regarding what users SHOULD see 
by default , decided that showing file extensions is a bad idea in general. 
Therefore, the default mode is for extensions (at least for "known file 
types") to be turned off. The extensions are NOT DELETED; they are simply 
not displayed. Also, the default display setting for the file information 
for System and Hidden files is to not be displayed. So, be aware that if you 
think you are "hiding" a file by setting its attribute to hidden, you don't 
hide it from everyone.
