Extract text from digital tachograph files (DTR)
To convert DTR tachograph files to another format, you need Azure Service Fabric or other Data software.
To convert other file formats to the "System Log & Telemetry" file type, you need software like Azure Service Fabric or a similar tool.
A .DTR file typically functions as a digital tachograph data file for commercial vehicles, securely recording driving periods, speed, and distance. It is also utilized by Microsoft Azure Service Fabric as a diagnostic trace log file to monitor distributed cloud applications. In rare cases, it acts as a DATroniC Data Recording file utilized by AFT equipment.
To open tachograph .DTR files, specialized fleet management software paired with a company or driver smart card is required. Azure Service Fabric traces are managed via the diagnostic tools available on the Microsoft Learn platform.
The main disadvantage of .DTR files is their highly restrictive nature. They are either secured, encrypted binary data blobs (to prevent legal tampering) or complex, domain-specific telemetry logs. Standard text editors cannot read them, and dedicated software often requires an expensive monthly subscription. Standard online converters consistently fail because they lack the specific parsing logic or decryption keys needed to extract the data.
Converting these files to standard CSV, XML, or TXT is highly recommended for data analysis, system auditing, or importing into third-party databases. Fleet managers frequently export tachograph data to PDF for compliance reporting. Be aware that strict encryption prevents direct conversion of tachograph data without authorized hardware.
Because this file format is heavily encrypted and proprietary, it is exceptionally difficult to open or convert manually. Often, only the original hardware or Azure platform can properly read or export the data. However, just drag and drop your file onto convert.guru to identify the format, view its structure, and convert it when possible. If our analysis detects an embedded text or XML structure, viewing or conversion may still be successful.
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.
If you want to convert DTR file to DB, SQLITE, SQLITE3, MDB, ACCDB, DBF, ODB, FDB, GDB, MYD, FRM or SQL, you can use Azure Service Fabric or similar software from the "Tachograph Data Recording & Logging" category. In the File menu, look for Save As… or Export….
To convert NDF, SQLITE3, BAK, RDB, SQL, DB4, MDF, MDB, LDF, DB, DB3 or SQLITE files to DTR, try Azure Service Fabric or another comparable tool in the "Tachograph Data Recording & Logging" 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 DTR converter.
