http://www.explorerxp.com/ is another file manager application. It has some great and new features. The greatest feature is TABS. You can open any number of tabs as you want. This provides a greater accessibility to any folder you want, and also dual view is history, because you can open 2+ tabs at once and tile them horizontally/vertically. This is what i wait for years.
It also has GROUPS feature that you can group folders and open them with one click.
But of course it is not as fast as xplorer2

If xplorer2 has these TABS and GROUPS features, it will be the greatest application on the market.
