Packages

These packages are recommended to be installed using yay to add in some features Dolphin may not include by default:

  1. dolphin-plugins to add version control and Dropbox support.

  2. kio-gdrive to add Google Drive directly into Dolphin.

  3. ffmpegthumbs to support video thumbnails in Dolphin.

  4. libheif to support HEIF (HEIC) images in KDE Plasma.

  5. kimageformats to add support for additional image format plugins.

Service Menus

Dolphin service menus add additional features directly to Dolphin's context menu.

  1. Some Dolphin service menus can either be installed using a package manager or helper such as yay, while others may require manual download and installation from the KDE Store.

    For the latter, create the service menus directory for your user:

    mkdir -p ~/.local/share/kio/servicemenus

    Alternatively, create the directory system-wide:

    mkdir -p /usr/share/kio/servicemenus

  2. Install the following recommended service menus accordingly:

    [!WARNING]
    At least some of these service menus are not guaranteed to work on KDE Plasma 6.

    • office2pdf to add Office documents conversion to PDF:

      • Manual installation:

        cp office2pdf.desktop <service-menus-directory>

    • KDE 5 Service Menu PDF to add more PDF-related functionalities:

      • Install the kf5-servicemenus-pdf package using yay.

    • KDE 6 Service Menu ReImage to add support for extra image-related functionalities:

      • Install the kf6-servicemenus-reimage package using yay.
      • You may also need to install some optional dependencies such as jhead for converting PNG images to JPG.
