How can I install games on a different drive using Heroic Launcher?

If you're using something like Bottles for managing games, you can set fake drive letters that point to your actual Linux folders. I gave my Bottles instance permission to access /mnt/Programs/ through Flatseal and mapped that to a 'D drive.' So when I install games, I can select that location right in the installer interface. It might be worth checking if Heroic Launcher or other similar tools have a feature like this.

It sounds like you're dealing with Flatpaks, which tend to be sandboxed and have limited access to your file system by default. You might want to check out Flatseal to manage these permissions. One way I do it is by creating a symlink to the storage drive in my home directory. This lets the application see that link and access files more easily. Give that a try—it's pretty straightforward!

All your Flatpak apps, including Heroic Launcher, keep their files in the .var directory. Since they're sandboxed, they can't interact with everything automatically. Using Flatseal can help you configure permissions. For instance, I have configured Flatseal to allow my game managers to access directories like /mnt/Programs/. Make sure you check the settings in Heroic Launcher too—there's usually an option to designate where your games are stored.
