Software preservation methodology

Software preservation methodology involves systematically safeguarding and maintaining digital software so it remains accessible, usable, and understandable over time. This process includes documenting software’s design and function, using formats that resist obsolescence, and storing copies properly. It also involves emulation or virtualization techniques to run outdated software on modern hardware, ensuring historical or valuable programs stay available. The goal is to prevent loss of digital heritage due to technological changes, ensuring future generations can access and study software as part of cultural and technical history.
