Convert aw to pgm

What is the difference between .aw and .pgm?

Description: The AW file type, standing for Answer Wizard File, is associated primarily with Microsoft Office applications, particularly with Microsoft Word and its integrated help system. AW files are designed to store indexes and data used by the Answer Wizard feature, enabling users to search for and receive help or answers to questions about using Microsoft Office programs. The Answer Wizard offers a more intuitive way for users to find assistance by allowing them to type questions in natural language, after which it searches through its database of AW files to provide relevant help.; A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.
