What is a TZX file?
A .TZX file typically belongs to one of two completely different software ecosystems. Most commonly, it is a ZX Spectrum tape image. This format preserves the exact audio data structure of original cassette tapes used by the Sinclair ZX Spectrum 8-bit home computer. It allows modern systems to run classic retro games and software.
Alternatively, a .TZX file can be a TimeZero Exported Data file. Marine navigation software from TimeZero uses this format to export user data, such as routes, marks, and waypoints. Internally, this marine data file uses standard ZIP compression.
How to open TZX files?
Because the .TZX file extension has multiple possible meanings, you must know the source of your file. If it is a retro computer file, you need a ZX Spectrum emulator like Fuse to load the virtual tape.
If the file contains marine navigation data, you should import it into TimeZero Navigator. Because these navigation files use ZIP compression, you can also rename the file extension to .zip and extract the contents using standard archive software like 7-Zip.
Software and tools
- ZX Spectrum Emulators: Open-source emulators like Fuse support the game-related .TZX format.
- TimeZero Navigator: Commercial marine software by TimeZero creates and opens navigation .TZX files.
- Archive Utilities: Command-line tools and software like 7-Zip can unpack the marine variant.
Inspecting TZX files online
Because .TZX has multiple possible meanings, we recommend using viewer.online/tzx to identify the actual format of your file. viewer.online/tzx can analyze .TZX files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
Whether you are managing classic 8-bit computer games or transferring complex marine navigation routes, viewer.online/tzx is useful for identifying, inspecting, and understanding .TZX files without installing software or dealing with compatibility problems.
