At this time, programs that use their own file pickers can only access at least Samba network shares via /run/user/<UID>/gvfs/<share name>. It would be nice to have that linked to a more visible location (probably in the home folder) by default. I had to search a bit to figure out the correct folder, and less experienced users might do worse.
Seems I was wrong, and they aren't accessible via a regular directory at all when using only Dolphin. I think they were only there because I had also opened the network folder with Nautilus/Gnome Files. Quite annoying deficiency not present in other desktops and OSes.
They are not accessible via smb:// ?
That's not a regular directory, as in /path/to/some/file. This is a problem mainly for CLI work, but also for what I had mentioned before.
(In reply to thisguy642 from comment #3) > That's not a regular directory, as in /path/to/some/file. This is a problem > mainly for CLI work You can mount Samba shares using the command line, see, e.g., https://wiki.samba.org/index.php/Mounting_samba_shares_from_a_unix_client I see that it would be desirable to have easy access to Samba shares in applications that do not use the KDE file dialog, but this is completely unrelated to Dolphin - the file manager might not even be running while you use the non-KDE application, so there is no way that Dolphin could provide access to the share! And even if Dolphin is running, it uses the KIO framework to access anything, including Samba shares, so this would have to be implemented in KIO. I think that bug 75324, which is about making KIO behave more like gvfs and mount kioslaves in regular directories, is what you mean, right?
