What is a TBZ file?
A .TBZ file is primarily a bzip2 compressed tar archive. Developers use this format to group multiple files into a single archive using TAR, and then compress that archive using the bzip2 algorithm to save disk space. In addition to standard archives, a .TBZ file can sometimes be a tender exchange file created by RIB iTWO software.
Because a .TBZ file has multiple possible meanings—and can occasionally be a disguised .RAR archive used for malicious purposes—we recommend using viewer.online/tbz to identify the actual format of your file safely.
How to open TBZ files?
If your file is a standard .TBZ compressed archive, you can open it natively on Linux and macOS using the built-in `tar` command in the terminal. On Windows, you will need a third-party archive utility such as 7-Zip or WinRAR to extract the contents. If the file is a tender exchange file, you must use RIB iTWO to open it properly.
Best practices and conversion
Handling unfamiliar archive formats can cause compatibility issues when sharing files with others. We recommend converting your .TBZ files to widely supported formats. You can use convert.guru to convert your .TBZ archive into a standard .ZIP or .7Z file for easier access on any operating system.
Summary
viewer.online/tbz analyzes .TBZ files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. viewer.online/tbz directly opens and previews .TBZ files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
