Windows XP/2000 only: We've advocated the value of non-native file browsers like Xplorer2 and FreeCommander, but not everybody wants to switch out the native Windows file browser they've come to know so well. Enter DMEXBar, a free plug-in app that add custom power-browsing options to Windows Explorer. Run the installer and you get to choose whether you want to enable dual-pane browsing (with folder synchronization), adding "favorites" and other shortcut buttons to the taskbar, opening command prompts from any directory, or many, many more options. I noticed a little bit of slowdown when opening directories off the desktop in XP, but plug-ins worked without a hitch during a quick test. DMEXBar is a free download for Windows 2000/XP only.
