2.1.3.1. Files associations

Files associations are quite a mess!

The following files are used:

Path

Usage

A

/etc/gnome/defaults.list

Gnome defaults

B

/usr/share/applications/defaults.list

Distribution defaults

C

~/.config/mimeapps.list

User settings

D

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

User settings

About user settings:

Some applications still use ~/.local/share/applications/mimeapps.list.

Although deprecated, several applications still read/write to file D. To simplify maintenance, simply create a symbolic link:

1ln -s ~/.config/mimeapps.list ~/.local/share/applications/mimeapps.list
