What is a DIZ file?

Files that contain the .diz extension are descriptor files that describe the different files that are contained in a ZIP file. A ZIP file contains multiple files that have been compressed into a single file, making it easier to distribute the files and freeing up storage space. The DIZ file is saved in plain text format and describes what is contained in the ZIP file.

DIZ files were common back in the days of bulletin board systems, where users dialed in and uploaded and downloaded software. The file_id.diz file in the ZIP files were used to generate the file listings on the BBS.
