AART is a specialized file format associated with the TeX typesetting system, originally developed by computer scientist Donald Knuth. It serves as a precompiled document template or resource file that stores macro definitions and layout structures to accelerate the processing of text outputs. While this format is largely legacy and used internally for memory dumps, it is inherently safe and presents no security risks during standard document compilation.
