Adobe PageMaker is a desktop publishing software that was widely used in the past for creating and designing publications such as brochures, flyers, and newspapers. Although it has been discontinued by Adobe, it still remains a popular choice among designers and publishers due to its ease of use and compatibility with older systems. The portable version of Adobe PageMaker 7.0.1 allows users to carry the software with them on a USB drive or other portable device, making it easy to work on different computers without the need for installation.
