Had to replace my hard drive. Before I started, I installed Sokoban on my laptop, transferred some files and verified that the indicators showing what levels were already solved was still there. So, I thought I was home-free to replace the drive. After reinstalling all, I copied the files back from the laptop, but did not get the indicators. Even if I copy the entire Sokoban 2 folder with all subfolders, I still do not get the indicators. Where are the information about solved levels stored? Or are there some export-import functions?
