Prerequisite

Before creating the actions (which are desktop files), first create its directory/folder by copy-pasting the below command in terminal:

mkdir -p ~/.local/share/file-manager/actions

The last two directories in the above line have now been created recursively. You can as well create them one inside the other by file manager. If you prefer this method and can’t see the first hidden directory (.local) in your Home (~/) press Ctrl+h to make it (and all hidden files and directories) appear.

Below actions are just examples. You can use them and create your owns based on them.

“Edit as root” custom action

Create and edit the action file (rootedit.desktop) either by using file manager or by issuing these terminal commands one at a time (replace juffed with your text editor if it’s different):

touch ~/.local/share/file-manager/actions/rootedit.desktop
juffed ~/.local/share/file-manager/actions/rootedit.desktop

Paste the below content in rootedit.desktop:

[Desktop Entry]
Type=Action
Name=Edit as Root
Icon=dialog-password
Profiles=profile-zero;

[X-Action-Profile profile-zero]
Exec=gksu juffed %f
Name=Default profile

Replace juffed with your text editor if it’s different and replace gksu with kdesu if you use kdesu.

“Set as wallpaper” custom action

Create and edit the action file (wallpaper.desktop) either by using file manager or by issuing these terminal commands one at a time (replace juffed with your text editor if it’s different):

touch ~/.local/share/file-manager/actions/wallpaper.desktop
juffed ~/.local/share/file-manager/actions/wallpaper.desktop

Paste the below content in wallpaper.desktop:

[Desktop Entry]
Type=Action
Name[en]=Set As Wallpaper
Icon=user-desktop
Profiles=profile-zero;

[X-Action-Profile profile-zero]
MimeTypes=image/*;
Exec=pcmanfm-qt -w %f
Name[en]=Default profile
SelectionCount==1
