Continuous Acquisition and Life-cycle Support Type 1 Image (.cal)

The CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.

The ICO file extension, standing for "Icon", is integral to Microsoft Windows for storing icons of different sizes and color depths. Its primary use is to display graphical representations of executable programs, files, and folders within the Windows operating system. The ICO format's origins trace back to the early versions of Windows, evolving over the decades to support enhanced resolutions and alpha transparency. Today, ICO files ensure visually consistent and scalable icons that maintain their appearance across various display settings, aligning with modern user interface standards.
