What is an LSB file?

LSB files mostly belong to Divinity Engine 2.

LSB files are used by different software tools, and their purpose depends on their origin.

Divinity Game Files: These files store save game data and game information for Divinity: Original Sin 2 from Larian Studios. They work with the Divinity Engine 2 or Divinity Engine 4. For more details, visit the Larian Studios website.
Linux Standard Base Files: In some cases, LSB files follow Linux standards. They may be used as parts of systems (like executables in a Linux Sandbox) or even as audio files (for example, linked with Final Fantasy VII). See more on the Linux Standard Base page or Linux Containers.
LightWave Scene Files: Other LSB files are tied to graphic data. They can refer to the concept of the Least Significant Bit in image processing or to LightWave Scene files used with LightScribe Simple Labeler.
Game Save and Script Files: A few instances use a JSON structure for game saves (like Levelhead save files) or work as script files for music notation in Lilypond, as seen with Paper Lily Studio. Additional information can be found at the RobTop Games website or the Paper Lily Studio website.

FilExt.com tip: Identify which software created your file and use that program to open and view its contents. Always back up your file before making any changes.

LSB file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format.
