How can I assign custom icons to folders?
Custom icon selection
In the file manager (nautilus):
- right click a folder's icon
- click on properties in the contextual menu
in the properties window click on the framed icon (top left)
- that should open the dialog to choose a new icon
Pick an icon from
/usr/share/icons
the default folder icons are in the Humanity sub-folder.
Custom icon backup & restore
The informations seems to be saved by nautilus in ~/.local/share/gvfs-metadata.
Note that the directory contains lots of other data (emblems and more). As far as I know they are in binary format so I wasn't really able to pinpoint what's really needed in a backup. Still file path of the icons shuld remain exactly the same between backup and restore for this to work
