Windows/Mac/Linux: Navigating through your hard drive contents can be slow and tedious at times, requiring double-click after double-click as your drill through your filesystem. Hawkscope addresses that by showing the contents of your drive—quickly—via a dynamic popup menu.
While running, Hawkscope sits in your system tray (or your menu bar if you're on a Mac). Right clicking the icon shows you an immediate popup menu of your hard drive(s). From there, you can navigate deeper into any folder's contents or open the current folder.
In the settings menu you'll find the option to turn on the global hotkey function (Windows/Linux only) which opens the menu directly under your mouse cursor. You can customise the drives and folders you want to show by creating quick access locations. Taking it in another direction, you can also hide unwanted drives, folders and files by adding them to a blacklist.
As if it weren't already useful enough, Hawkscope supports the use of plugins—six currently available—which add a host of cool features, including unread items from your Gmail account, instant access to your Delicious bookmarks, and—you guessed it—Twitter integration. Hawkscope is a free and open-source app for Windows, Mac OS X, and Linux.
