Extract text from RDI files
To convert your RDI file to another format, you need WinADCP or other Data software.
To convert other file formats to the "Scientific Data Logging" file type, you need software like WinADCP or a similar tool.
The .RDI extension is shared by two distinct but technical file types: Teledyne RD Instruments raw data files and Rohos Disk Encryption images.
Most commonly encountered in oceanography and geology, this file contains binary raw data recorded by Acoustic Doppler Current Profilers (ADCP). These files (often created by WinADCP or VMDAS) store complex hydroacoustic measurements.
The Problem: The format is a proprietary binary stream. You cannot open it in Excel or Notepad. Scientists and engineers frequently struggle to access the velocity, echo intensity, and correlation data locked inside without specialized, expensive software.
Best Conversion Targets:
Alternatively, an RDI file may be a virtual encrypted disk container created by Rohos Mini Drive. These act as secure, portable vaults for sensitive files.
The Problem: This is a "container" file. You cannot "convert" it directly to a PDF or JPG. It must be mounted using the correct password and software to reveal the files inside.

Convert.Guru analyzes your RDI file, detects the exact format, and lets you read the text inside.
If you want to convert RDI file to BASE64, HEX, BIN, ENC, CRYPT, AES, DES, RSA, PGP, GPG, ASC or KEY, you can use WinADCP or similar software from the "Raw Scientific Data Storage" category. In the File menu, look for Save As… or Export….
To convert CER, BIN, PEM, DER, KEY, P7S, PFX, ENC, P12, BASE64, P7B or HEX files to RDI, try WinADCP or another comparable tool in the "Raw Scientific Data Storage" 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 RDI converter.
