Extract text from SPEFO or RecordFlux files (RFI)
To convert RFI data files to another format, you need AdaCore or other Data software.
To convert other file formats to the "Integration & Spectral Data" file type, you need software like AdaCore or a similar tool.
The .RFI file extension typically serves two distinct technical functions: it is either a SPEFO Stellar Spectra Analysis Data file used in astronomical research, or a RecordFlux Integration file used by the AdaCore developer toolkit. In addition to these formal formats, it is incredibly common for users in the construction or project management industries to incorrectly save a standard "Request for Information" document by manually typing .rfi as the file extension instead of .pdf or .docx. For astronomical data, the files are created and accessed using the legacy DOS/Windows software SPEFO. In systems engineering, AdaCore's toolkit parses .rfi files as standard YAML to define state machine buffer sizes.
Because of this fragmented usage, handling an .RFI file can be frustrating. SPEFO files contain proprietary, niche data matrices that modern spreadsheet or analysis tools cannot natively interpret. The format is heavily outdated, restricting researchers to obsolete software environments. For developers, RecordFlux files are plain text, but the obscure .rfi extension prevents standard IDEs from automatically applying YAML syntax highlighting. Meanwhile, misnamed documents completely break the file association in Windows or macOS, rendering standard files "unopenable" to the average user.
To make these files usable, converting them to standard formats is essential. RecordFlux integration files should be converted or simply renamed to YAML or TXT to restore full compatibility with code editors. If the file is a misnamed document, identifying its true nature and converting it back to PDF or DOCX is the only way to read it. True astronomical SPEFO data is notoriously difficult to open or convert because only the original software can properly map and export the stellar measurements. Our platform can inspect the internal file signatures, extract human-readable text, and detect if a supported underlying or embedded format is present, ensuring that viewing or conversion may still be possible even when standard converters fail.
Convert.Guru analyzes your RFI file, detects the exact format, and lets you read the text inside.
Users also converted PVR, BIN and EQW files.
If you want to convert RFI file to , you can use AdaCore or similar software from the "Astronomical Data & System Integration" category. In the File menu, look for Save As… or Export….
To convert files to RFI, try AdaCore or another comparable tool in the "Astronomical Data & System Integration" 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 RFI converter.
