About D files

The .D file extension primarily represents source code written in the D Programming Language, a high-performance systems language. These files are plain text documents containing instructions for compilers like DMD or GCC. A secondary but widespread use is for Dependency Files generated by build automation tools like GNU Make, which map out relationships between source code and header files.

While developers use these files daily, general users often encounter .d files in confusing contexts. Chromium-based browsers (e.g., Google Chrome, Microsoft Edge) generate internal .d cache files that are not meant for manual opening. Additionally, niche industrial software like GEWISS CAD creates proprietary .d electrical project files, which are locked to specific software versions and expensive licenses. Opening these without the original environment is a frequent downside.

Best Conversion Targets:

For Documentation/Sharing: Convert D source code and dependency text files to PDF to preserve formatting for code reviews or archiving.
For Quick Viewing: Convert to TXT or RTF to make the code readable on any device without installing an IDE.
For CAD/Schematics: If your file is from GEWISS software, converting to PDF or JPG is the only way to share the visual design with clients who do not own the GBG-V software.

Convert.Guru analyzes your D file, detects the exact format, and lets you read the text inside.

Users also converted MP4, PDF, BIN, ENC, CBP, DEPEND, PL, R, F and I files.

The D Converter Story

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 D converter.
