-Steam downloads the Windows version of a Proton-enabled app, but still stores files in the familiar `~/.steam/steam/steamapps/common/[appname]` directory. On first launch, Proton provisions a Wine prefix (created in `~/.steam/steam/steamapps/compatdata/[appid]` by default) that holds pertinent state data and a basic Windows filesystem in `$WINEPREFIX/pfx/drive_c`. This filesystem is presented to the app as its root Windows filesystem. Save games are usually stored in the prefix as well, making save game import [complicated](https://www.brainvitamins.net/blog/mass-effect-savegame-import/).
