QT TabBar is an add-on for Windows Explorer that enables you to enjoy new, improved functionalities in your system's standard file manager. These new features include the ability to use tabs in Windows Explorer to open different folders simultaneously, plus the possibility to browse subfolders by means of a context menu instead of having to open each folder separately.

The program also allows you to create folder groups, preview file contents in a tooltip and open applications with customized hotkeys, amongst other extended functionalities.
