What is a KEV file?

KEV files mostly belong to Tracealyzer.

Kernel Event Log File: This KEV file is most often a kernel event log used in software tracing. It stores low‐level system events that developers use to analyze operating system behavior. Tools like Tracealyzer can read these files to show event sequences and debug issues. When this file is produced by tracing software, it may contain binary data representing interrupts, scheduling events, and other kernel activity.

Killzone Extraction Map
In other cases, a KEV file may be a Killzone Extraction map used by Killzone 2. This type of file holds game map data and sometimes appears as a data file in security software like Kaspersky Endpoint Security or in applications such as Knytt Stories. To open these, specific game extraction tools or utilities that support the game data format are needed.

If you have a KEV file, determining its origin is important. Identify the context: if it is a system trace, use a tracing tool; if it is game-related, seek a game map viewer.

How can I open a KEV file?

You need a suitable software like Tracealyzer to open a KEV file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your KEV file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a KEV file directly in the browser:. Just drag the file onto this browser window and drop it.
