About DIZ files
The .diz file extension has two completely different use cases, both of which cause modern compatibility headaches. Historically, it stands for "Description In Zip" (famously named FILE_ID.DIZ) and is a simple plain text file used in the Bulletin Board System (BBS) and shareware/warez scenes to describe the contents of an archive. Modernly, the .diz extension is also used by the Italian Revenue Agency, the Agenzia delle Entrate, for telematic tax declarations.
The main disadvantage of classic .diz text files is that operating systems like Windows and macOS do not recognize the extension natively. Double-clicking one triggers an annoying "Choose a program to open this file" prompt, even though the file only requires a basic text editor like Notepad. The formatting is also severely restricted, lacking any modern markdown support. On the other hand, Italian tax .diz files are completely unreadable out of the box because they are actually renamed ZIP files containing hidden XML or PDF documents. Users cannot access their tax data without knowing this technical workaround or installing clunky government software.
To solve these issues, you need to convert or extract the files. For text descriptions, convert your .diz to TXT for basic editing, MD for web markdown, or PDF for permanent archiving and easy sharing without OS warnings. For Italian tax files, you should convert or extract the hidden ZIP contents to access the internal documents.

The DIZ Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DIZ converter.
