Extract text from tachograph data files (DCA)
To convert DCA data files to another format, you need Stoneridge OPTAC or other Data software.
To convert other file formats to the "Driver Card Archive" file type, you need software like Stoneridge OPTAC or a similar tool.
A .DCA file most commonly functions as a Driver Card Archive containing digital tachograph driver data. These files record driving times, speeds, and rest periods for commercial fleet compliance and are typically managed by fleet software like Stoneridge OPTAC. Historically, .DCA also stands for Document Content Architecture, an obsolete IBM text format used by software like IBM DisplayWrite. Additionally, the Italian Agenzia delle Entrate uses .DCA for tax data exchange via their Docet software, which are internally structured as ZIP archives.
The main disadvantage of a .DCA tachograph file is that it is a raw, proprietary binary dump protected by cryptographic signatures. You cannot open it natively in a web browser, and it requires a commercial fleet management subscription to decode properly. For IBM DCA files, the primary issue is complete obsolescence - modern word processors dropped support decades ago.
To make this data readable or ready for audits, users often need to convert these files into CSV, TXT, or PDF. Standard online converters usually fail to process .DCA files because they misinterpret the encrypted hex data or do not support legacy IBM architectures.
This file format is difficult to open or convert because tachograph .DCA files are highly specialized regulatory formats where only the original software can properly read, validate, or export the data. If our analysis detects a supported underlying or embedded format - like the standard ZIP structure of the Italian tax data files - viewing or conversion may still be possible.
Convert.Guru analyzes your DCA file, detects the exact format, and lets you read the text inside.
Users also converted MP3, CDA, PDF, WZ, GPK and EZ files.
If you want to convert DCA file to MP3, TXT, RTF, DOC, DOCX, ODT, PAGES, TEX, LATEX, MD, MARKDOWN or LOG, you can use Stoneridge OPTAC or similar software from the "Digital Tachograph Driver Data" category. In the File menu, look for Save As… or Export….
To convert PDF, DOC, ASC, TODO, NFO, MEMO, README, DOCX, JPG, TXT, NOTE or RTF files to DCA, try Stoneridge OPTAC or another comparable tool in the "Digital Tachograph Driver Data" 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 DCA converter.
