From KDE TechBase
    This page describes an old version of KioFuse which does not compile on recent system (anything based on Qt5 or newer). It is kept for historical reference.

    KioFuse allows you to mount remote directories into the root hierarchy of your local file system, thereby exposing KDE's advanced access capabilities (SSH, SAMBA/Windows, FTP, TAR/GZip/BZip2, WebDav, etc) to POSIX-compliant applications such as Firefox, OpenOffice, GNOME apps, shell utilities and more.

    Usually, you would browse an FTP-server with firefox, but with KioFuse you can use Dolphin for that alternatively.

    Another important advantage of KioFuse is that it allows you to arrange the hierarchy of all your remote, archived and compressed files in whichever way makes sense to you.

    KioFuse works by acting as a bridge between KDE's KIO filesystem design and FUSE.


    • Install kdelibs (version 4.0 or higher) provided by your Operating System or compile it according to these (non-existing) intructions.
    • Type the following commands into a terminal:
    svn checkout svn://
    cd kiofuse
    cmake .

    Running KioFuse

    • Mount with:

    kiofuse --mountpoint <mountpoint> --URL <URL>

    • Unmount with:

    fusermount -u <mountpoint>

    Real-world example: (Though in the actual real world no one would do this since clicking on a *.tar.gz file in Dolphin just enters the ZIPfile without further ado. If anything, kiofuse here slows down the user's workflow if he were to follow this guide.)

    # Create the mount point
    mkdir ~/fuse-source
    # Download the compressed archive of the FUSE source code
    wget -P ~
    # Mount the archive in ~/fuse-source
    ./kiofuse --mountpoint ~/fuse-source --URL tar:~/fuse-2.7.2.tar.gz &
    # Browse the source code in your favorite filemanager without ever needing to unpack the archive!
    dolphin ~/fuse-source &
    nautilus ~/fuse-source &
    thunar ~/fuse-source &


    Features and TODO

    • Some KIO slaves such as tar: don't support seeking and therefore won't be able to read or write to files. Fixing these slaves is on the TODO list.
    • KIO needs to be modified so that it is aware of KioFuse mounts and so that it uses its native functions (as opposed to POSIX) to access those resources.
