IconViewer - Version 1.1 IconViewer is a slick little free add-on for the Windows Explorer Properties window that serves as an icon viewer. Select an icon-laden file (.exe, dll, .etc.) and access the Properties dialog from the right-click context menu. You'll see a new Icons tab that shows all the icons contained in the file. Also, the device images (32x32x16 colors, 48x48x256 colors, etc) for each icon are displayed.
