About TLZ files
The .tlz file extension represents a compressed archive, primarily functioning either as a TTCN-3 Test Log Archive or an Lzip Compressed Tar Archive. In the telecommunications and software testing industry, it stores execution logs adhering to the ETSI TTCN-3 standard. In Unix/Linux environments, it functions as a tarball compressed using the Lempel-Ziv-Markov chain algorithm (LZMA) or Lzip compressor. To open these archives locally, users typically rely on specific software like TestLogAnalyzer for test logs, or general extraction tools like 7-Zip and GNU Tar.
The primary disadvantage of the .tlz format is poor native compatibility. Windows and macOS do not natively recognize Lzip or LZMA compressed tarballs, and opening them requires third-party software installation or command-line execution. This creates a bottleneck when sharing test results or system archives with non-technical users.
To ensure maximum compatibility across all operating systems, extract or convert the archive to a standard ZIP file. If you need immediate access to the raw TTCN-3 testing data, extract the contents directly to TXT or XML. Drag and drop your file to analyze and convert it - free, online, and without installing software.
Convert.Guru analyzes your TLZ file, detects the exact format, and lets you read the text inside.

The TLZ 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 TLZ converter.
