Extract text from Cadastral and tax files (DTW)
To convert DTW Data files to another format, you need AGKK Cadastre Software or other Data software.
To convert other file formats to the "Localized Government File" file type, you need software like AGKK Cadastre Software or a similar tool.
The .DTW file extension is primarily associated with two highly specific, localized data systems: Bulgarian cadastral data files used by the Bulgarian Cadastre Agency (AGKK) and German tax and health insurance declaration files associated with Kaufmännische Krankenkasse (KKH). A smaller, legacy subset of these files contains Desktop Wallpapers from Morgan Wireless.
Opening these files typically requires the exact proprietary software that generated them, such as regional CAD and GIS tools for Bulgarian land registries or German financial software for KKH billing.
The main disadvantage of the .DTW format is its strictly proprietary and closed nature. These files are not supported by standard web browsers, document editors, or mainstream GIS software. Because they contain highly localized, structured data that is often encoded, users outside of these specific government or financial portals cannot read them. Standard online converters will fail to process them because the encoding schemes are closed-source.
Depending on the file's origin, users often want to convert Bulgarian cadastral .DTW files to standard vector formats like SHP or DXF, while German financial data might need to be exported as CSV or XML for auditing.
This file format is incredibly difficult to open or convert because often only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your DTW file, detects the exact format, and lets you read the text inside.
Users also converted RAL, TRK3 and DTP 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 DTW converter.
