How to Back Up and Save your Internet Explorer Favorites
Internet Explorer's favorites list is where you keep a list of all of the sites that you like to visit. If something should happen to your computer or you wish to try one of the other popular browsers, a backup of your favorites list will be needed.
Launch Internet Explorer and click the "Favorites" button. Click the drop-down box arrow next to the "Add to Favorites" button and select "Import and export."
Select "Export Favorites" and click "Next." Select which favorite folders you wish to export. This will also create a file that you can use as a backup.
Review the filename and save location. By default, IE will name the file "bookmark.htm" and place it in your Documents folder. To call it something else or save it elsewhere, then make those changes. Click "Next" to proceed.
Click "Finish." Import the file to other browsers, such as Google Chrome or Firefox.
