Extract text from backup indexes (BKI)
To convert BKI indexes to another format, you need DriverBackup! 2 or other Backup software.
To convert other file formats to the "Driver Backup File" file type, you need software like DriverBackup! 2 or a similar tool.
A .bki file is a device driver backup file created by DriverBackup! 2, an open-source utility used to save Windows system drivers. These files store hardware metadata, paths, registry keys, and the actual driver components (like INF, SYS, and DLL files) necessary to restore hardware functionality after a system wipe.
However, the .bki format has significant disadvantages. It is a closed, proprietary archive. You cannot browse the contents natively in Windows File Explorer or standard archive managers. Because the original software is old, users frequently face compatibility issues on modern operating systems and are unable to access their saved drivers.
To safely access your hardware drivers, we recommend converting .bki files to ZIP archives. This allows you to manually extract the raw driver files for installation via the Windows Device Manager. Alternatively, converting the internal metadata to TXT or XML helps you read the hardware list without installing the original program.
This file format is difficult to open or convert because it relies on specific NET serialization. Often only the original software can properly read or export the data. However, just drag and drop your file to convert.guru to identify the format, view it, and convert it if supported. If our analysis detects a supported underlying or embedded format, extracting the drivers or viewing the text is still possible.
Convert.Guru analyzes your BKI file, detects the exact format, and lets you read the text inside.
Users also converted RBC, LBF and QDF-BACKUP 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 BKI converter.
