Expose directories

The Bottles Flatpak is sand-boxed and confined in its directories. It make use of portals to let you open and save files in other directories.

Despite this, there are some cases where you may want to explicitly expose directories to the Flatpak, e.g.:

• let the Importer find windows prefixes from other managers directories

• use the file chooser provided by the runner to open/save files in your system, outside the sandbox

To achieve this, we need to use an external program named Flatseal, it can be easily installed from Flathub using a compatible store like GNOME Software, elementary Appcenter or Discover. It is also possible to install trough the command line:

flatpak install com.github.tchx84.Flatseal

On first launch you need to select Bottles from the left menu, then scroll to the Filesystem section and make your choices.

We suggest to not expose all your system or home but manually add each directory in Other files. In the following example we are exposing the ~/Games folder from our home (the default location for Lutris windows prefixes).

Then the Bottles Importer will see the new directory.
