About LCS files
An .LCS file is a highly fragmented extension used for multiple unrelated internal application purposes. Most commonly, it acts as a cache, contact list, or conversation history file for Microsoft Lync (now Skype for Business). It is also widely used as a game save file for Grand Theft Auto: Liberty City Stories, a game data file for League of Legends, or a catalog signature component for Symantec LiveUpdate. You typically need the exact creating software, such as Skype for Business, Symantec System Recovery, or the specific game engine to natively open or utilize these files. The major disadvantage of .LCS files is their complete lack of standardization. Because the extension is claimed by dozens of developers for background tasks, the files are almost always proprietary, closed-source binary, or encrypted. For example, LockLizard uses .LCS for secure software license distribution, which explicitly prevents tampering or unauthorized viewing. Users frequently encounter these files taking up unexpected disk space as endlessly growing application caches that cannot be read by text editors. Direct conversion is rarely practical or possible for cache and license files. However, if the file is a Lync contact list, the ultimate goal is usually to get the data into CSV or VCF format. If it is a GTA game save, players sometimes want to extract the embedded PNG screenshots. This file format is notoriously difficult to open because it relies entirely on the internal logic of the specific application that generated it. Standard online converters will fail completely because they cannot guess which variant of .LCS you possess. If our analysis detects an underlying standard like a ZIP container (used by LockLizard) or a Microsoft Compound Document (used by Symantec), extracting the raw data or embedded media assets is still achievable.
Convert.Guru analyzes your LCS file, detects the exact format, and lets you read the text inside.

The LCS Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our LCS converter.
