I use Xubuntu with kubuntu-desktop.
ST2 has an option “Open containing folder…” when you do right-click on source-code screen. On my Ubuntu a stupid Gwenview was opened instead of usual File manager.
I removed Gwenview. And now nothing is opened when I choose “Open containing folder…”.
How can I connect the option “Open containing folder…” with a file manager on my system so that this file manager will be opened?
