Tabbed browsing and dual pane for file dragging are the 2 killer features I always dreamt of in Windows Explorer. I just waited and waited hoping M$ to get it right for the file explorer.
But wait no more as I found QtTabbar and been actually using it for a year now. Recnttly shifted to new PC and started missing it badly after few days.
There are 2 or 3 other similar tools I have seen but this keeps on winning me (like so many others) due to its ‘no fuss’ nature and ‘does not come in between’ ability (and its free by the way).
Its here on sourceforge, find out for yourself.
Note: this tool will be a life saver for Windows 7 or earlier versions. Windows 8 has done some enhancements to explorer, you may want to compare features.
