What is a KL file?

KL files mostly belong to Text Editor. An KL file can mean several things depending on its origin.

Android Key Layout File: This file defines how hardware keys map to actions on an Android device. It is a plain text configuration that tells the system which key codes correspond to each key. For syntax details, check the Android reference.

Keyman Keyboard Layout: Here the file holds custom keyboard mapping data for the Keyman software. It helps in creating layouts that allow users to input different characters efficiently. More details are available at the Keyman website.

KUKA Robot Language File: In industrial settings, a KL file might be used as a program file to instruct robot movements. This file contains code or instructions for robot control. Visit the KUKA website for further specifics.

Compressed Colmap Data: Some KL files are archives compressed with the 7z format and used to store Colmap data. To view these, a decompression tool like 7-Zip is needed.

FilExt.com tip: Since each version serves a distinct purpose, inspect the file’s content using a plain text editor or the appropriate tool if the file appears binary. This will help you decide whether you are dealing with a key layout configuration, a robot instruction file, or a compressed archive.

How can I open a KL file?

You need a suitable software like Text Editor to open a KL 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 KL file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a KL file directly in the browser:. Just drag the file onto this browser window and drop it.

KL file format details:

A file format defines how the data in the file is structured. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the KL files is as follows:

KL is not that commonly used as a file extension. This file type covers different formats for different programs. But the following two file formats are common:

• 25% of all KL files start with the bytes # Copyright (, which are crucial for this file format. The content consists of readable text data, which can be read using a text editor. The files are on average 1 KB in size and range from 810 bytes to 9 KB. The file type was created 10 years ago, but is still used today. The files contain the following words: # Licensed under the Apache License, Version 2.0 (the "License");, # You may ob, # you may not use this file except in compliance with the License and # Copyright (C) 2010 The Android Open Source Project. The file name Generic.kl or AVRCP.kl is typical for these files. Such files are related to product, vendor and qwerty.
• 20% of all KL files have the same signature 00 00 00 00 00 00 00 00. They consist of illegible, cryptic characters. A typical file size is 250 bytes. Certain words are almost always found in the files, such as !"#$%&. Some examples of file names are en-US.kl or de-DE.kl.

The remaining 55% of all KL files are different files with different signatures, frequently e.g. ZIP, 7z, PROGRAM and key. Files like these are sometimes linked to list, gpio, keys, corailwagen or continuity. If you want to find out what your KL file contains, drag and drop it onto this page.
