Extract text from Ragnarok files (RGZ)
To convert RGZ files to another format, you need Ragnarok Online or other Game software.
To convert other file formats to the "Patch Archive" file type, you need software like Ragnarok Online or a similar tool.
The .RGZ file extension is most frequently associated with Ragnarok Online, the classic MMORPG developed by Gravity. These are Ragnarok Game Zip files - proprietary compressed archives used to deliver patches, including new sprites, background music (BGM), and executable updates to the game client. Technically, they function similarly to standard GZ or .TAR.GZ archives but utilize a custom header structure that prevents standard tools from opening them automatically.
For most users, the main challenge is that .RGZ files are "black boxes." Windows and macOS treat them as unknown files, and double-clicking results in an error. While the game's internal patcher handles them automatically, server admins and modders often need to inspect or modify the contents. The files are often left behind in the game folder after a failed patch, taking up disk space. A secondary, distinct use case exists in geophysics, where .RGZ files are compressed data logs generated by Metronix ADU (Analog Digital Unit) data loggers. These contain electromagnetic measurement data and are completely incompatible with game tools.
To access the contents of a Ragnarok .RGZ file, the most pragmatic solution is to use 7-Zip, which can often detect the underlying GZIP compression. For full extraction of complex patch archives, specialized community tools like GRF Editor are recommended. If you are dealing with Metronix data, the file must be processed using Mapros or converted to MTH5 format for scientific analysis. For general archiving, converting the extracted contents to standard ZIP is best for compatibility.

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 RGZ converter.
