What is an LCS file?

LCS files mostly belong to League of Legends. LCS files are not a single file type but a file extension used for several purposes.
For example, some LCS files act as license files used by companies like ZTE UMS and ProtectDisc. These files store licensing information to validate and activate software.
Other LCS files are used by games such as League of Legends and LittleBigPlanet. In these cases the files may hold game data (save files, configuration files, or even screenshots in a PNG container).
Additional uses include:

A Link ECU configuration file from Link ECU Manager – used to log and set up parameters for vehicle systems (LinkECU).

An SQLite database that may store conversation history for systems like Microsoft Lync (SQLite website).

A Lotus 1-2-3 script or a Lotus Screen Show file – these relate to spreadsheet and presentation tasks.

A log file in Microsoft Compound format such as a Cisco switch system check log (Cisco).

To open and view an LCS file, you should first identify its origin. Use the corresponding vendor software – for license files, use the license manager provided by the company; for game data, use the game client or a dedicated editor; for ECU or log files, use the specialized management tool provided.
Visit ZTE Global or Protect Software for license file details, and check other vendor sites for configuration or database information.

How to open an LCS file

LCS file extension format:

To find out what program is needed to open LCS files, you need to determine the file format. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the LCS files is as follows:
