Extract text from DM2 files
To convert your DM2 file to another format, you need IDERA ER/Studio or other Database software.
To convert other file formats to the "Entity-Relationship Diagram" file type, you need software like IDERA ER/Studio or a similar tool.
A .dm2 file is most frequently a proprietary Data Model diagram created by IDERA ER/Studio (formerly Embarcadero) or the legacy Toad Data Modeler. These files contain complex Entity-Relationship (ER) diagrams, physical database schemas, and logical data flows essential for database architecture. A major drawback of .dm2 files is the strict vendor lock-in; they are binary or specialized XML formats that cannot be opened by standard text editors or generic diagramming tools like Visio. This forces stakeholders - such as project managers or developers without expensive licenses - to rely on static exports.
For documentation and review, the best workflow is converting these diagrams to PDF or high-resolution PNG images, allowing the schema to be viewed universally. If you are dealing with the less common Quake II demo recording (also a .dm2 extension), the file is a game replay, not a video; to share it, you must replay it inside the Quake II engine and screen-capture it to MP4 or AVI.
Convert.Guru analyzes your DM2 file, detects the exact format, and lets you read the text inside.
Users also converted KIT, SKT, LBE, DM3, M2 and CM2 files.
If you want to convert DM2 file to M2, CM2, DM3, CSV, JSON, XML, YAML, YML, TOML, INI, CFG or CONF, you can use IDERA ER/Studio or similar software from the "Data Model Diagram" 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 DM2, try IDERA ER/Studio or another comparable tool in the "Data Model Diagram" 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 DM2 converter.
