- Description
 - An ALS file is an image created with Alias SketchBook Pro, a painting and drawing application for mobile devices and computers. It contains a drawing created with the software, which may include layers, colors, text, and images. ALS files also store additional information about the drawing such as the name of the author.
 - An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
