The CALS Raster File Format is a bitmap defined by the U.S. Department of Defense and intended for storing monochrome images.
There are two types of *.cals files:

1. Type 1: Stores a single image per file and data is always compressed using CCITT Group 4.

2. Type 2: Can store multiple images per file, the image data for each image can be subdivided into tiles, and each tile can be stored uncompressed, or compressed using CCITT Group 4.

Mime types:
image/x-cals

This cals file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
