Extract text from DRO files
To convert your DRO file to another format, you need DOSBox or other Audio software.
To convert other file formats to the "FM Synthesis Capture" file type, you need software like DOSBox or a similar tool.
The .dro extension primarily refers to the DOSBox Raw OPL format, a captured audio log used by retro gaming enthusiasts. These files record the raw FM synthesis commands sent to the OPL2 or OPL3 chips (like the Sound Blaster or AdLib cards) during gameplay. Users typically convert these to MIDI, WAV, or MP3 to listen to vintage game soundtracks on modern devices without running the emulator. A common downside is that .dro files are not standard audio files; they are instruction logs that require an OPL emulator to generate sound, making them unplayable in standard media players like VLC or Windows Media Player.
A secondary but significant use case (approx. 15%) is the Electricity Meter Data Readout generated by Iskraemeco smart meters. These binary data logs store power consumption metrics for utility billing and analysis. They are strictly proprietary and often require the Iskraemeco MeterView or Symbiot software to open or convert into human-readable formats like CSV or XLS for Excel processing.

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 DRO converter.
