There isn't much to complain about in PowerDesk Utilities. It would be nice if there were a few more options for the configurable toolbars (large/small icons, with/without text labels, etc.), and the interface could also benefit from being a bit more polished (and more in line with the Windows 98/2000 interface).
But overall, if you're a power user looking for more versatility and functionality than the regular Windows Explorer provides, PowerDesk is the perfect alternative. And even if you aren't currently looking for an Explorer replacement, you'll still want to check out the multitude of supporting utilities that can help make working in a Windows environment more productive and efficient.
Pros: A natural born Explorer-killer with excellent file manager tools, freeware edition
Cons: Interface is somewhat outdated and could also use a bit of polish, customizable toolbars need more config options
