While Windows Explorer is definitely several steps up from the Windows 3.x File Manager, for many power users Explorer still doesn't quite get the job done. Windows Explorer lacks advanced features like customizable toolbars, options for multiple window panes, folder comparison and synchronization tools, the ability to change fonts and other layout controls, and file filtering capabilities. The lack of configurability alone is enough to send many power users on a search for something better.
Thankfully, there now are alternatives to the Windows Explorer, and one of the best has to be the inexpensive PowerDesk Pro from VCOM Products (formerly from Ontrack Software).
PowerDesk has actually been around for several years, but only the most recent releases have been able to integrate advanced features and functionality into an interface that is professional and powerful enough to serve as a viable replacement for Explorer.
