Okay, I know about going into Windows Explorer | Tools | View and selecting the option to hide extensions for known file types. I usually leave it unchecked, which means, in Windows explorer, mysong will display as mysong.mp3. No problem there.
However, about a month ago, I made the stupid mistake of upgrading Internet Explorer V7 to V8. I should have left well enough alone with IE7 and Chrome, but IE8 gave me so many problems I uninstalled it and rolled back to IE7. Now, all my links, on the Links bar, in my Favorites folders ans subfolders are showing the extension of .URL for every address. Needless to say, besides being irratating, it takes up space on the links bar.
Thje only way I seem to be able to disable it is to follow the stpes abpve and select to not show extensions of known filetypes, but them I don't see them in Windows Explorer. Is there some was to disable .url from showing? It never did before installing and removing IE8.
