file-managergnome3
I just switched to Fedora 22 and decided to go for Gnome3 this time instead of XFCE. I like the Thunar file manager so I downloaded it. I've had trouble setting it as the default file manager though.
What I tried:
I ran exo-preferred-applications. Under Utilities -> File Manager I selected Thunar.
The problem:
It's not acting as the default file manager. When I open my Downloads folder from my browser I still get Nautilus. Same when I click on my "Places".
The idea is to already have the needed programs in the 'Open with' context-menu for a selected folder without the need to select "Other application".
Editing the line inode/directory= in /usr/share/applications/mimeinfo.cache is not useful because, as indicated in a comment by don_crissti, the problem re-appears after an update or a program install because of the command update-desktop-database.
In fact only some programs will take over the file manager role as indicated by the question, but those that do will in some cases take over directly, simply after their installation, and will do again after update-desktop-database.
As suggested here by the aforementioned user, you need to edit ~/.local/share/applications/mimeapps.list like:
[Default Applications]
inode/directory==nemo.desktop;audacious.desktop;deadbeef.desktop;vlc.desktop
In another system (Cinnamon Manjaro, where there is no mimeapps.list in usr/share/applications, only mimeinfo.cache and seems non-freedesktop-complient) the file to use is ~/.local/share/applications/mimeinfo.cache with a content like
[MIME Cache]
inode/directory==nemo.desktop;audacious.desktop;deadbeef.desktop;vlc.desktop
It is essential to put the file manager first and then the programs to add to the 'open with' context menu.
For example, the above will give
What you can do is:
It should be persistent now
Alternatively you can set the entry in ~/.config/mimeapps.list in the [Default Applications] section.
