About CDZ files
The .cdz file extension primarily represents a Compressed PlayStation Disc Image used by the ePSXe emulator and other legacy gaming emulators. These files store compressed game data to save hard drive space compared to standard BIN or ISO dumps. Another significant use for .cdz files is as an Electronic Data Interchange (EDI) document generated by Comarch EDI systems. These specific EDI files are internally structured as ZIP archives to facilitate business-to-business data transfer. Less commonly, the extension is used as an installer archive for ChamSys MagicQ lighting control software.
The main drawback of the .cdz format is its highly specialized, proprietary nature. For PlayStation games, it utilizes a non-standard compression method that many modern emulators do not support natively, forcing users to keep obsolete software installed. For EDI documents, the data is often locked behind proprietary enterprise software, making it difficult to read the raw transaction data without a paid commercial subscription.
To improve compatibility, you should convert a game image .cdz to an uncompressed ISO or BIN format, though this will significantly increase the file size on your drive. For Comarch EDI files, extracting the internal archive to access the underlying XML or CSV data is the best approach.
This file format is difficult to open or convert because its internal structure depends entirely on the source software. Game images use custom compression algorithms, while EDI files are designed for machine-to-machine communication rather than human readability. Often, only the original software can properly read or export the data. Just drag and drop your file to identify the format, view it, and convert it when possible. If our analysis detects a supported underlying or embedded format, viewing or extracting the content may still be possible.
Convert.Guru analyzes your CDZ file, detects the exact format, and lets you read the text inside.
If you want to convert CDZ file to BIN, ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE or ARJ, you can use ePSXe or similar software from the "Compressed PlayStation Game Image" category. In the File menu, look for Save As… or Export….

The CDZ 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 CDZ converter.
