He actually doesn't need to turn it on. It's the default behavior for a Win2K (or frankly, for a Win9X) installation. You have to explicitly turn it OFF. > When he adds the extension manually, he actually ends up with a file > called "xxxxx.pdf.pdf" and the system hides the second one. Which is precisely why it should be turned off, **always**. This is how the "I Love You" virus worked. Attached to the email was a file that looked like "iloveyou.txt", but was actually "iloveyou.txt.vbs", a Visual Basic script. The default behavior of Windows hid the real extension, fooling recipients into believing they were merely openning a text file. > Ask him to go into tools -> folder options -> view, and then untick the > box "Hide file extensions for known file types". That won't do; the default, again, is for changes to that option to apply only to the folder he's viewing. He must perform the action you suggested, then apply it, *then* click the "Like Current Folder" button at the top of the dialog box. Once he accepts the message that follows, it will be properly set. -- -Bob James Pentar InfoSystems www.keyserver.net KeyID FEBEC3DB
