Overview

ICO is a Microsoft Windows icon format.

ICO files can have multiple icon images of different sizes in the same file, so that programs displaying them can pick the size that is appropriate for a particular use. Image data within the file is either in BMP or PNG format, with some header bytes defined by the ICO standard.

CUR (cursor) files are in a nearly identical format with only a few bytes different.
