Turn on file name extensions

By default, Windows Me hides file name extensions for all known file types, which is fine if you're in Details view. But you many want to see extensions in other views—and some e-mail programs may even have difficulty recognizing attachments without them.

To turn on extensions:

1. On the Tools menu in Windows Explorer, click Folder Options.
2. Click the View tab.
3. Clear the Hide file extensions for known file types check box.

Note   You can set or remove this option for individual folders by opening the folder and following the steps above.
