New version! -IconViewer is a freeware product developed by Bot Productions. It is a utility that allows you to view the icons contained within files, such as executable files and dynamic link libraries (DLLs). IconViewer is a shell extension, a plugin for Windows Explorer. When you open the Properties box for a file containing icons, an extra Icons tab will appear. Clicking on this tab brings up the IconViewer property page, and it lists the icons that the file contains.
