Where Does Lucas Chess Store Data?
Lucas Chess keeps training data and PGNs in its own Documents folder, with engines and config beside the saves.
Last updated
Lucas Chess centers on one Documents folder. Training progress, played games, and engine configs sit inside it where file managers browse freely. The layout stays stable across versions, which makes moves boring in a good way.
Copy the folder whole with the program closed and the new install continues cleanly. Engines travel as files but run better reinstalled natively on the new system. Confirm the folder after first launch, since it appears once the program writes initial state.
Where Lucas Chess stores this, by platform
%USERPROFILE%\Documents\Lucas Chess
Training data, games, and engines in one Documents tree. Copy it whole with the program closed. PGN files inside open anywhere.
Frequently asked questions
How do I move Lucas Chess to a new PC?
Copy the Lucas Chess folder to the same Documents path on the new machine. Training data, games, and settings travel together. Engines need reinstalling separately on the new system.
Where are Lucas Chess game files?
In the same Documents tree as plain PGN text, openable in any chess tool. Copy the files out regularly, since they outlive every install and version change.
