Quick Question: Why some icon support large icon some doesn't?

[Limyx826]

Here is a screenshot of a folder where I set to Extra Large Icon.

As you see there are two icon that are stuck in medium size. May I ask why?

Hi, icons can be made up of several pictures (of different sizes) all together in 1 file. For example, most icons contain a minimum of a 16x16 picture and a 32x32 or 48x48 picture.

Icons are basically embedded into a program when it's created. So if the icon that is used for a program only has a 32x32 icon, that's all you will see.

Example: The first icon has multiple pictures included (see them on the right). The 2nd icon has 2 pictures, the last icon has 1 picture. See how they look in Explorer below that.

You can always create a shortcut to a program and use a custom icon for the shortcut. You just need to find a good high resolution icon with multiple images in it.
