Extract text from DFI files
To convert your DFI file to another format, you need Battery Management Studio or other Data software.
To convert other file formats to the "Configuration Image" file type, you need software like Battery Management Studio or a similar tool.
The .DFI extension is notoriously ambiguous, serving as a container for battery calibration data, legacy disk images, and digital forensics indices. Most frequently, you will encounter this as a Data Flash Image generated by Texas Instruments Battery Management Studio (bqStudio). These files store critical fuel gauge parameters for Li-Ion battery packs. The friction here is high: the format is binary and proprietary to TI's ecosystem, meaning you cannot simply open it in a text editor to view the hex values or calibration constants. Engineers often need to convert these into human-readable CSV reports or SREC (Motorola S-record) firmware files for mass production programming.
Alternatively, if you are dealing with legacy industrial automation, your .DFI file is likely a Disk Factory Image created by Rockwell Software. These are archaic sector-by-sector copies of floppy disks used for software authorization. Since modern PCs lack physical floppy drives, these files are effectively bricked unless converted to a standard IMG or ISO format for use in virtual machines like VMware or VirtualBox. Less common variants include Digital Forensics Framework indices and ASUS Express Gate firmware, both of which are heavily resistant to standard conversion tools.
Convert.Guru analyzes your DFI file, detects the exact format, and lets you read the text inside.
Users also converted FW, 300 and 301 files.
If you want to convert DFI file to , you can use Battery Management Studio or similar software from the "Battery Management Data" category. In the File menu, look for Save As… or Export….
To convert files to DFI, try Battery Management Studio or another comparable tool in the "Battery Management Data" 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 DFI converter.
