DIZ File

Did your computer fail to open a DIZ file? We explain what they are used for and recommend software that we know can open or otherwise handle your .DIZ files.

What is a DIZ file?

A .DIZ file is a 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.

What else are .DIZ files used for?

While Description in ZIP-file is a popular type of DIZ-file, we know of 2 different uses of the .DIZ extension.

The DIZ file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a DIZ opener may not be able to open all kinds of DIZ files. In this case, look through both formats to make sure you find the best suited DIZ viewer.

Diz compressed data

These DIZ files contain data compressed by "diz", a free, experimental, open-source file compressor by Roger Flores. It is a PPMC based compressor written in Python. You will need to uncompress the data in order to access it.
