Steam vs MS Store encrypted folders / permissions lock, install paths, DRM

For a transfer to another computer - I’m guessing you’ll need at least to reinstall the base part of the game, which as of Sim Update 6 is about 1.6 GB. Then you can take that 110 GB of Packages (Community + Official) and copy it to the new machine. Start the MS-Installer, and point it to the new Packages path where that 110 GB exists. It may need to add/update a few more files but then you should be good to go.
