Extract text from RWD files
To convert your RWD file to another format, you need Symphonie Data Retriever or other Data software.
To convert other file formats to the "Measurement Log" file type, you need software like Symphonie Data Retriever or a similar tool.
The .RWD extension is primarily associated with Raw Wind Data logs generated by NRG Systems Symphonie series data loggers. These binary files capture critical meteorological measurements - such as wind speed, direction, and temperature - used in renewable energy site assessment. A secondary but significant use of the format is for RheoWin data files produced by Thermo Fisher Scientific rheometers, measuring the flow and deformation of matter.
Because .RWD files are proprietary binary containers, they present a major accessibility challenge: they cannot be viewed in standard tools like Microsoft Excel or text editors. To analyze this data, engineers and scientists must typically process the files through the specific manufacturer's software (e.g., NRG Symphonie Data Retriever) to apply scaling factors and export meaningful engineering units. For broader accessibility, archiving, or analysis in third-party tools like MATLAB, users frequently convert .RWD files to universal plain text formats like CSV (Comma Separated Values) or TXT.
Convert.Guru analyzes your RWD file, detects the exact format, and lets you read the text inside.
Users also converted ZIP, SOS, NCP, OMD, AWD and FWD 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 RWD converter.
