Yup. One of the options with Windows 2000 (and XP) is to NOT display known file extensions. If your friend turned that option on, then he won't see the ".pdf" or ".doc".
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
