Sometimes you accidentally delete something you really shouldn't have. Here's how to restore a deleted favorites folder.
First, navigate to the Recycle Bin on your computer's desktop. It should look like a trash can with some paper in it.
Double click to open the recycle bin.
Find the favorites you accidentally deleted.
Right click on it, and click on "restore."
Open Internet Explorer. Your favorites should be restored.
If you've emptied your Recycle Bin since accidentally deleting the favorites, you will not be able to recover them.
