What is a II file?
Information file created by IconWorkshop, a program used for creating custom icons for Mac OS, Windows, and Unix; stores metadata associated with an image or icon, including the title, description, author, and keywords.
II files are used by IconWorkshop's librarian for indexing and enhanced search capabilities. They are created as hidden files and are given the same name as their corresponding media file except with the added ".ii" extension.
