Extract text from DTR files
To convert your DTR file to another format, you need TachoTools or other Data software.
To convert other file formats to the "Telemetry Log" file type, you need software like TachoTools or a similar tool.
A .dtr file is most frequently a Digital Tachograph Data file, a legally mandated format used in the logistics industry to record vehicle speed, distance, and driver activities (like rest periods). These are binary, encrypted containers designed to be tamper-proof, meaning you cannot simply double-click to open them in Notepad or Microsoft Word. Fleet managers often face the challenge of needing to convert these proprietary raw files into human-readable PDF reports for compliance or CSV formats for payroll analysis without breaking the digital signature validity.
Alternatively, a .dtr file may be a Trace Log generated by Microsoft Azure Service Fabric. These diagnostic files contain system events and errors used by developers to debug cluster issues. They are typically large, binary-encoded, and require specialized parsing tools like Azure Service Fabric Explorer or custom scripts to extract readable text. Less commonly, the file might be a DATroniC data recording created by AFT MARC 4CAN software for ECU calibration.
Convert.Guru analyzes your DTR file, detects the exact format, and lets you read the text inside.
Users also converted DLT, RCRM and METRICLOG files.
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 DTR converter.
