IconButler has many functions to manage icons. IconButler is using 'Icon Library' file format (extension '*.ICL' ). In this 'icon container' you can save icons needing disk space like a zip file without unzipping the file getting a single icon from it...

IconButler handles 256 colors icons () and 16x16 pixel icons too. To edit an icon using the right mouse key context menu you have to associate the '*.ICO' extension with an Icon Editor. Additionally it is possible to extract Icon from files (*.DLL, *.EXE).
