Extract text from Depth maps and puzzles (ZT)
To convert ZT Depth maps to another format, you need 7-Zip or other Compressed software.
To convert other file formats to the "Compressed Archive File" file type, you need software like 7-Zip or a similar tool.
The .ZT file format typically serves as a Geocaching puzzle file associated with the Geocaching Zit tool, or it functions as a renamed 7-Zip compressed archive. In rare cases, it acts as a Mental Ray Image Depth File utilized by Autodesk rendering software.
Users primarily encounter .ZT files when downloading custom puzzle caches from the geocaching community or receiving specifically branded archives. You can generally open the archive variants using 7-Zip or standard unzipping software because they rely on common underlying compression frameworks.
The main disadvantage of the .ZT format is its obscure extension. Neither Windows nor macOS natively recognizes .ZT files, meaning default tools and web browsers fail to open them. This forces users to manually assign programs or guess the actual format, creating unnecessary friction when trying to access basic compressed data.
The most practical conversion targets for these files are standard ZIP or 7Z archives. Extracting or converting the file into a universally recognized format restores access to the embedded texts, images, or GPS coordinates without losing data quality or requiring niche geocaching software.
Dealing with unrecognized extensions is a frustrating experience, especially when the underlying data is accessible. Just drag and drop your file to identify the format, view it, and convert it when possible. convert.guru will inspect the file's internal signature to confirm if it is a standard ZIP archive, a 7z file, or a proprietary 3D rendering file, letting you bypass the confusion entirely.
Convert.Guru analyzes your ZT file, detects the exact format, and lets you read the text inside.
Users also converted 7Z, CG, TVP, NVU and RON files.
If you want to convert ZT file to RON, OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL or PLY, you can use 7-Zip or similar software from the "Geocaching Puzzle Data Storage" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to ZT, try 7-Zip or another comparable tool in the "Geocaching Puzzle Data Storage" category.
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 ZT converter.
