LSL	File extension: LSL
	File type:	text-based file

What is an LSL file?

LSL files mostly belong to LiveSplit. LSL files are not a single file type but are used in different ways.
For one set, these files are XML-based configuration files that store layout settings such as timer designs and label templates. They are used with applications like LiveSplit for managing split or layout information and with the LightScribe Template Labeler for printing labels.

LiveSplit Layout File: Contains settings that determine how a speedrun timer is displayed. More details can be found at LiveSplit.
LightScribe Label: Holds template information for printing labels on compatible devices.

Another group of LSL files is based on the Linden Scripting Language used in virtual worlds such as Second Life. These are plain text files containing script code that controls behaviors and actions within a virtual environment. More information is available on the Second Life website.
How you open an LSL file depends on its role. Use a plain text editor or a specialized XML/code editor when modifying layout or script files.
Tips include:

Backup the file before making changes.

Use editors with XML validation or code syntax highlighting.

Test any script modifications in a safe environment.

How to open an LSL file

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

How to solve problems with LSL files

Associate the LSL file extension with the correct application.
Update your software that should actually open text-based files. Because only the current version supports the latest LSL file format. Search, therefore, e.g. on the manufacturer website after an available LiveSplit update.
To make sure that your LSL file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
