About KLG files
A .klg file is a system or application log file, most commonly generated by Sophos antivirus software as a Kernel Log, or by KOFIA financial applications. These files record background events, driver interactions, and error codes necessary for software troubleshooting.
You can generally open plain text .klg files with standard text editors like Notepad++ or Microsoft Notepad.
The main disadvantage of the .klg format is its obscure extension, which causes modern operating systems to fail to recognize it automatically. Double-clicking it usually prompts an annoying "How do you want to open this file?" dialog. Furthermore, some .klg files (such as those generated by stealth keyloggers or proprietary enterprise tools) are written in undocumented binary formats or are heavily obfuscated to prevent tampering. Standard online converters fail to process them because they do not understand the proprietary log structure.
The best conversion target is TXT for universal readability, or CSV if the log data is structured with delimiters. Converting to a standard text format ensures you do not need specialized software to review the logs in the future.
This file format is often difficult to open or convert if it is a proprietary binary log. Emphasize that often only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded text format, viewing or conversion may still be possible.
Convert.Guru analyzes your KLG file, detects the exact format, and lets you read the text inside.

The KLG Converter Story
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 KLG converter.
