About GDP files
The .gdp file extension is primarily used for Game Data Package files associated with the ShineEngine game engine, as well as Game Data Archive files used in the CINEMAX Gumboy game series. These files act as proprietary containers holding essential game assets such as textures, audio tracks, 3D models, and level data. In the case of the Gumboy games, the .gdp file is simply a renamed ZIP archive. The main disadvantage of the .gdp format is its obscured, closed nature. Most file managers and operating systems will not recognize it out of the box, forcing users to rely on specialized modding tools or manually guess the underlying compression method to access the files. If you need to edit or view the assets, the best approach is extraction rather than direct conversion. The best conversion targets for extracted game assets include PNG for textures, MP3 or WAV for audio, and standard archive formats like ZIP or 7Z for repacking the files. Because these files are proprietary game containers, standard online converters usually fail to process them. They are designed exclusively to be read by their specific game engines. However, convert.guru can still help. Just drag and drop your file to identify the format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format (like a standard ZIP archive), viewing or conversion may still be possible.
Convert.Guru analyzes your GDP file, detects the exact format, and lets you read the text inside.

The GDP 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 GDP converter.
