Files that contain the .icl file extension are usually associated with Windows desktop shortcuts. These files contain a collection of icons that can be used to replace the existing icons that are used for shortcuts on the user's computer desktop.
The ICL files themselves do not contain any actual program file data, just icon image files that are used to create a shortcut for the associated applications. For example, if a user wishes to change the icon of a particular program shortcut on his or her desktop, he or she can select a different image from within the collection of icons in the ICL file.
