ATK is a raster image file format associated with Andrew Toolkit, a set of tools for distributing documents that contain embedded objects. The format was developed as part of the Andrew Project, launched at the Carnegie Mellon University in the United States, in the early 1980s. The project resulted in the development of several other types of computing infrastructure tools too, and was considered an important step for making such tools more accessible at the time.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple ATK files as once.
