What are DIZ files and how to open them

Are you having problems opening a DIZ file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your DIZ files.

What is a DIZ file?

DIZ files have multiple uses, and Description in ZIP- is one of them. Read more about the other uses further down the page.

Description in ZIP-file

Files containing the .diz extension are descriptor files that describe the different files 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.
