Can't get USB drive exposed to Bottle

[methanoid]

I can set the drive D for example as /mnt/media/james/HDMI-CAP (name of USB drive) and it stores that but when I start the program and go to open a file and select D in the dialog nothing is shown.

Probably a user error but I can't see anything to help me in the docs?

What are your file system permissions for the Bottles flatpak? Have you modified them or are they the default permissions?

[methanoid]

Defaults PLUS something (cant find now) that came from Flatpak website for adding ability to read outside the default places (sorry to be vague, thought I had bookmarked that page). I'd check now but I had to wipe my install and re-do and havent added that Bottle yet....

If you have not done so already, try using Flatseal and giving Bottles explicit permission to access the path where your usb is mounted.

I am having the same problem, though not specifically with USB drive. Using v51.9 (stuck there due to #3218 -- no fault of the Bottles team). Fundamentally, the problem is that I've got Flatpak, Bottles, and Wine between me and my goal, and I don't know any of them well enough to succeed. The goal is simply to have one specific folder accessible to one specific bottle. Steps I have taken:

• Using Flatseal, in the Filesystem section for Bottles, add ~/Projects under Other files. (As an aside, what does the Persistent section do that is different?)
• In Bottles, in the bottle settings under Compatibility->Manage Drives, map P to Projects. I see a symlink added for dosdevices/p:. (Another aside, Bottles adds symlinks for d:: -> /dev/sdc and e:: -> /dev/sdc1. I can't remove them in Manage Drives, and if I delete the symlinks Bottles recreates them. What's up with that?)
• Using Legacy Wine Tools->Configuration I map P: to ~/Projects.

In Legacy Wine Tools->Explorer, P: appears but is empty. In Command Line, "p:" returns "Path not found." and "dir p:" returns "File not found." If I create a symlink to ~/Projects anywhere under drive_c, that folder appears is both Explorer and Command Line, but again shows as empty and returns "File not found."

What is it I am missing? Thanks!

Ok, wait, I just tried something new which gave partial success... Looking at my running processes, I manually killed these processes:

• 4072448 C:\windows\system32\winedevice.exe
• 4072458 C:\windows\system32\winedevice.exe
• 4072441 ~/.var/app/com.usebottles.bottles/data/bottles/runners/soda-8.0-2/bin/wineserver
• 4060952 bwrap --args 45 bottles

After doing this and running Bottles again, the symlink in drive_c works! So that means the Flatseal setting + symlink works, but requires everything to be fully shut down and restarted before taking effect.

Now the questions are:

• What is the correct way to shut everything down, rather than looking for processes and manually killing them? [Edit: Tried to reproduce this and can't. I don't know why those processes were hanging around before, but now they always exit cleanly as expected.]
• What am I missing that P: still doesn't work?
