Convert CTZ to another file type
To convert CTZ backups to another format, you need AVEVA CitectSCADA or other Backup software.
Convert a file to CTZ
To convert other file formats to the "SCADA Project Archive" file type, you need software like AVEVA CitectSCADA or a similar tool.
About CTZ files
The .CTZ file extension represents a few distinct formats, most notably a CitectSCADA project backup file, an EFILive vehicle performance tune file, or a CherryTree encrypted document. CitectSCADA uses the .CTZ format to store compressed project configurations, essentially functioning as a renamed ZIP archive. EFILive relies on the format to store engine control unit (ECU) parameters for vehicle tuning. Alternatively, the open-source note-taking app CherryTree uses .CTZ for password-protected, 7Z-compressed XML documents. Finally, AMD packages some driver security catalogs as .CTZ files.
Users often need to convert or extract .CTZ files to access the internal data without installing the original, often expensive or highly specialized software. The main disadvantage of these formats is their proprietary nature. EFILive files are strictly locked to specific tuning hardware, making them practically useless to standard users. SCADA backups require the heavy AVEVA software suite to properly restore and read the interface data. Standard online converters fail to process these files because they do not recognize the multiple underlying structures or understand how to parse automotive hexadecimal data.
The best conversion targets for a .CTZ file depend on its origin. If it is a CitectSCADA backup or a CherryTree file, you can often extract it to standard ZIP or 7Z archives to recover the underlying XML, TXT, or image assets. Converting EFILive files is much harder, as the tuning data is tightly encoded. This file format is difficult to open or convert natively because the data is either encrypted or relies on complex, proprietary directory structures. If our analysis detects a supported underlying or embedded archive format, viewing or conversion to common formats may still be possible.
Convert.Guru analyzes your CTZ file, detects the exact format, and lets you read the text inside.
If you want to convert CTZ file to BIN, ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE or ARJ, you can use AVEVA CitectSCADA or similar software from the "Project Backup & Vehicle Tuning" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to CTZ, try AVEVA CitectSCADA or another comparable tool in the "Project Backup & Vehicle Tuning" category.
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.
