What is a .DIZ File?

A .DIZ file is a small plain text file historically used in software distribution, especially in the early days of Bulletin Board Systems (BBS). The word DIZ stands for “Description in ZIP.” These files typically contain short descriptions of the software archive they accompany. When users downloaded ZIP files from BBS platforms, the included .DIZ file helped sysops and downloaders quickly understand what the archive contained.

Why Were .DIZ Files Popular?

Back in the 1990s, internet bandwidth was limited, and BBS operators needed ways to manage descriptions of uploaded files quickly. Instead of writing descriptions manually, they allowed the system to pull information from .DIZ files inside ZIP archives. This automated process saved time and created a standard format for file descriptions. Although the format is mostly historical today, it remains a nostalgic reminder of early file-sharing culture.
