RegFileExport is a new command-line utility for advanced users that allows you to easily extract keys and values from offline Registry file located on external hard-drive and export them into a standard .reg file of Windows. RegFileExport doesn’t load the file into a Registry hive like RegEdit, instead, it directly reads the Registry file and analyzes it.
RegFileExport may also be able to extract keys and values from the Registry file even if the Registry file is corrupted and cannot be loaded by Windows.
