Comment 3 for bug 191363

Thanks for your testing. Marking as Confirmed. Could be a simple as a Dolphin configuration. I run Gnome on most of my machines, I have KDE on a partition somewhere. If you right-click on the file and choose open with other application, then choose custom command:

What happens if you put a custom command that looks something like: (modify it to your environment)

wine exel.exe /media/myusbdevicethatisgivingmetrouble/myexelfile.xls

You can get device names using the command:

df -h

If this works, then you have a work around. If it doesn't then the Dolphin folks can figure out why usb mounted devices don't get the correct path sent to wine.

You can make launch icons on your desktop with this custom command if it's a file that you routinely edit.
