Ubuntu – Linux File Manager: Restore previous open session (folders and tab)

I had similar problems with the default file type program associations in ubuntu. You probably need to choose on of those in the list for the auto extract here options to work nicely. That does not mean that you cant change the default archive managing application.

These posts go into some detail about how to change the association manually by editing the files used to map file types with programs.

Where are file associations stored?

How can I change the default text editor from gedit to vim?

To change the stored associations, and priorities. ie which app show up first in a list have a look here.

gvim ~/.local/share/applications/mimeapps.list

Try creating a new entry in the open with menu. I am not sure this will work as different command line programs use different options. A little experimentation my be need to get this working correctly. The problem is most probably linked to the parameters that pacman passes to application.

First, to get 7z (or any app) into the "open with other application" list, you need to create a .desktop file in ~/.local/share/applications with a line in it like this: Exec=<command> %f. I just made one called 7z.desktop with these lines:

[Desktop Entry]
Categories=;
Comment=Edit file in Vim
Exec=7z %f
GenericName=Process Viewer
Hidden=false
Icon=vim
Name=Vim
Terminal=true
Type=Application
Version=1.0

Inspired by Mozilla Firefox Bug 727422, comment 30, I found out that Firefox is currently (FF 36.0, Ubuntu 14.10 with LXDE) using the org.freedesktop.FileManager1-Interface on the Dbus session bus. As stated in the specification of this interface, Nautilus (also known as Files) is the only file manager that implements this interface. Therefore, Firefox will always choose Nautilus as file manager if it is installed.

So there are two possibilities to resolve this first problem:

1. Uninstall Nautilus/Files
2. Tamper with the org.freedesktop.FileManager1-Interface that Nautilus offers to disable this method of Firefox to open a file manager. Therefore, you could just delete /usr/share/dbus-1/services/org.freedesktop.FileManager1.service. But maybe, it is a better approach to use the proposed solution of https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/133133/comments/74 and create ~/.local/share/dbus-1/services/org.freedesktop.FileManager1.service and set its exec-line to /usr/bin/false (just copy /usr/share/dbus-1/services/org.freedesktop.FileManager1.service there and change it). This avoids deleting/editing a file created by your package manager and you do not need super user privileges. After having done so, you possibly need a restart.

As soon as Firefox can not use the Dbus-Interface anymore, it will fall back to a second way to figure out which file manager to start. This will lead to the second problem:

The default applications should be configured with several different mimeapps.list-files with different priorities. It seems to me that Firefox is correctly consulting the files ~/.config/mimeapps.list, ~/.local/share/applications/mimeapps.list and /usr/share/applications/mimeapps.list but not the deprecated defaults.list-file. So, you have to add the inode/directory=pcmanfm.desktop-entry to one of the three files mentioned above. This can also be done by calling gvfs-mime --set inode/directory pcmanfm.desktop or xdg-mime default pcmanfm.desktop inode/directory.

Lxde itself seems to use ~/.config/lxsession/LXDE/autostart to determine its default file manager. Therefore, you have to edit one of those files manually.
