QTTabBar is Windows Explorer add-on that allows you to navigate files and folders in a tabbed browser, just like you do in IE7. The program, written in C#, works on any Windows XP or Vista (32-bit) machine with .NET 2.0+ installed. To get started, download the latest version and install the program. Reboot and logon to Windows again. Open a folder in Explorer and right-click on the toolbar. Check 'QT TabBar'. That's it! There's also a desktop toolbar available which you can access by right-clicking on the Task Bar and checking 'QT Tab Desktop Tool' in the 'Toolbar' menu. This is so convenient, I can't believe I hadn't heard of it before now!
