  1. File/folder structure within the installation folder reflects the path(s) listed for DOS and/or PC booter game data. For the GOG.com release, file changes in DOSBox are redirected to <path-to-game>/cloud_saves/ even if GOG Galaxy is not used (this folder contains all redirected files, so some files in the cloud_saves folder might be temporary files or other files that do not contain saves or settings).
