About CDZ files
CDZ files are most frequently Compressed Disc Images created for the legacy pSX emulator (also compatible with ePSXe). This format compresses standard BIN/CUE or ISO PlayStation game dumps using zlib compression to save disk space. While efficient for storage, the format is proprietary and lacks support in modern emulators like DuckStation or RetroArch, meaning you cannot play your games without converting them back to raw disc images. Additionally, these files cannot be mounted by standard virtual drive software like Daemon Tools.
Alternatively, a .CDZ file may be an Electronic Data Interchange (EDI) document generated by Comarch systems. In this context, the file is simply a renamed ZIP archive containing business documents (like invoices in XML or PDF format). The custom extension prevents operating systems from treating it as a standard folder, causing "unknown file type" errors. To access the data, users typically need to rename the file extension or use a dedicated conversion tool to extract the contents for viewing.
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 pSX Emulator or similar software from the "Compressed Game ROM" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to CDZ, try pSX Emulator or another comparable tool in the "Compressed Game ROM" category.
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.
