About CTZ files
The .ctz extension is a shared battleground for three distinct industries: industrial automation, automotive tuning, and personal knowledge management.
Citect SCADA Backup (Primary): Most commonly, this is a compressed project archive created by AVEVA Plant SCADA (formerly CitectSCADA). While these files effectively package complex industrial control projects, they create friction for engineers who need to quickly inspect code or graphics without installing the multi-gigabyte, licensed SCADA suite. These are essentially ZIP archives disguised with a proprietary extension.
EFILive Tune File: In the automotive world, .ctz files are calibration data used by EFILive to tune GM and Dodge engines. These are heavily encrypted and often locked to specific hardware (FlashScan), making them impossible to open with standard text editors or generic converters.
CherryTree Document: Users of the hierarchical note-taking app CherryTree use this format for password-protected or compressed notes. Under the hood, it is a 7-Zip archive containing an XML document.
Conversion Strategies:
For Extraction: Since Citect and CherryTree files are compressed archives, the best "conversion" is often renaming the file extension to ZIP or opening it directly with 7-Zip. This allows you to extract the raw XML, DBF, or image assets.
For Documentation: To share project details without requiring the original software, extract the contents and convert the internal text or logs to PDF.
For Tuning: EFILive files are binary-locked; they generally cannot be converted to open formats like CSV or BIN without the proprietary EFILive V8 software.

The CTZ 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 CTZ converter.
