Convert a file to STZ

To convert other file formats to the "Simulation Data Archive" file type, you need software like dSPACE ControlDesk or a similar tool.

About STZ files

The .stz file extension is a dual-use format that most frequently functions as a Stimulus Data Package within the dSPACE automotive simulation ecosystem. These files serve as compressed containers (essentially renamed ZIP archives) holding stimulus profiles, signal waveforms, and test vectors used for Hardware-in-the-Loop (HIL) testing and ECU validation. Engineers often face friction here because while the container is standard, the internal data structure is optimized for ControlDesk or AVL CAMEO, making it difficult to analyze signal data in Excel or MATLAB without first exporting it via the proprietary software suite.

Alternatively, in the gaming community, .stz refers to the Sonic Team Zip format, a compression archive used in titles like Team Sonic Racing. Unlike the automotive variant, these game archives often use custom compression algorithms that standard tools like WinRAR cannot natively handle. Modders and gamers looking to extract textures or audio assets typically encounter "unknown format" errors when trying to open them directly.

Conversion Recommendations:

For Data Analysis: If it is a dSPACE file, change the extension to zip to inspect the contents. Convert internal data to CSV or MAT for easy plotting.
For Game Modding: Use specialized extraction scripts (such as those for QuickBMS) to unpack assets into standard formats like PNG or WAV.
For Archiving: Extract all contents and repack into a non-proprietary 7z or ZIP container to ensure future accessibility.

Convert.Guru analyzes your STZ file, detects the exact format, and lets you read the text inside.

Users also converted 7Z, BOZ and OMS files.

The STZ 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 STZ converter.
