Extract text from PSP game data files (JRZ)
To convert JRZ game files to another format, you need ISO Master or other Game software.
To convert other file formats to the "PSP Game Data Archive" file type, you need software like ISO Master or a similar tool.
A .JRZ file is a proprietary game data archive utilized by PlayStation Portable (PSP) titles to store in-game assets. Developed by Sony, these files bundle crucial game components such as 3D models, level scripts, and VAG audio tracks into a single optimized container. Players and modders typically encounter .JRZ files when extracting data from a CSO or ISO disk image using utilities like ISO Master or PowerISO.
The primary disadvantage of the .JRZ format is its completely closed, undocumented ecosystem. Because it is a proprietary console format, it lacks native support on Windows, macOS, or standard web browsers. Users attempting to access the game's soundtrack or textures quickly discover that standard archive tools like 7-Zip cannot read the custom binary headers. Furthermore, modifying the file without specialized hex editors will instantly corrupt the game data, making modding incredibly difficult.
When users seek to convert a .JRZ file, they are usually looking to extract its contents into standard ZIP archives or convert the internal VAG audio to MP3 or WAV. However, converting the container itself is practically impossible with generic tools because the file is compiled exclusively for PSP hardware. Standard online converters fail to process .JRZ files because they do not recognize the proprietary magic numbers or compression algorithms. Even though the format is closed, our deep-file analysis can often detect standard embedded audio headers or text strings, giving you realistic workarounds for an otherwise inaccessible file.
Convert.Guru analyzes your JRZ file, detects the exact format, and lets you read the text inside.
Users also converted DMP files.
If you want to convert JRZ file to ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE, ARJ or LHA, you can use ISO Master or similar software from the "PSP Game Asset Storage" 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 JRZ, try ISO Master or another comparable tool in the "PSP Game Asset Storage" category.
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 JRZ converter.
