When editing, it is possible to open an executable file (exe, dll,
ocx, scr etc.), and library of ICL format. To open previously edited
icons libraries, you can use the history feature of the open
When editing an executable file you can not add/delete the icons,
change the sizes, color depth, or quantity of formats of the icon.
You can only change the images that already exist in the file. If
you attempt to open an icon
file, the program searches it for formats with the identical sizes
and quantity of colors and opens only them.
When editing an ICL library, all these restrictions are removed.
