Nikos Bozinis' 2xExplorer (a Windows Explorer replacement) has a neat but not so obvious feature. When you search for all files or folders with a certain pattern, 2xEplorer will display the search results window. Selecting an item in that window will cause the main window to jump to that item in your filesystem. The not-so-obvious feature is that when you delete items in the search results window, those items are deleted in your filesystem! This feature came in handy when I wanted to delete all CVS folders (to set up a new module) or all obj folders (to work around a Visual Studio bug).
