Extract text from Disk catalogs (DTC)
To convert DTC Catalogs to another format, you need ConceptDraw PRO or other Data software.
To convert other file formats to the "Multi-Purpose Data File" file type, you need software like ConceptDraw PRO or a similar tool.
The .DTC file format serves multiple, completely unrelated technical purposes. Most frequently, it functions as a disk catalog file for legacy Mac DiskTrak systems, or as a 2D network diagram generated by ConceptDraw PRO and the CADE vector editor. Alternatively, it is widely used as a Diagnostic Trouble Code log exported by automotive OBD-II scanners (like BlueDriver) and as European digital tachograph driver data.
Because the .DTC extension is heavily fragmented across different industries, it is notoriously difficult to open. Attempting to load an XML-based automotive diagnostic file into a CAD vector program will result in an immediate error. Furthermore, proprietary vector diagrams require expensive, specialized software installations just to view a simple network layout. The lack of native web browser support makes this format extremely frustrating to share with clients, colleagues, or mechanics.
Converting your .DTC file is the most practical workaround. For network diagrams and electrical CAD projects, convert .DTC to PDF or SVG for high-quality, universal viewing. If the file contains text-based diagnostic logs, tachograph data, or Microsoft JetDB database exports, convert it to CSV or XML to analyze the data in a spreadsheet.
Convert.Guru analyzes your DTC file, detects the exact format, and lets you read the text inside.
Users also converted DCT, CSV, BIN, TXT, PDF, DXD, MC, DLY and HEX files.
If you want to convert DTC file to HEX, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use ConceptDraw PRO or similar software from the "Diagrams & Diagnostic Data" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to DTC, try ConceptDraw PRO or another comparable tool in the "Diagrams & Diagnostic 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 DTC converter.
