Sharing bookmarks and favorites
Favorites, known as bookmarks in Netscape Navigator, are a convenient way to organize and link to Web pages that you visit frequently.
Internet Explorer automatically imports all your Netscape bookmarks. On the Favorites menu, click the Imported Bookmarks folder to view them.
If you use Internet Explorer on several computers, you can easily share favorites between computers by importing them. Also, if you use both Internet Explorer and Navigator, you can keep your favorites and bookmarks up-to-date with each other by importing them between programs.
To import bookmarks or favorites, click the File menu, and then click Import and Export.
To export favorites to bookmarks or favorites on the same or another computer, click the File menu, and then click Import and Export.
Notes
Exported favorites are saved as a regular HTML file, so either Internet Explorer or Navigator can import them. You can export a selected folder in your Favorites list, or all of your favorites.
The exported favorites file is fairly small, so you can copy it to a floppy disk or network folder, or attach it to an e-mail message if you want to share the favorite items with other people.
