Forked from PCManFM, SpaceFM is a lightweight, highly configurable, desktop-independent multi-panel tabbed file and desktop manager. It features a built-in virtual file system, a udev-based device manager, a customisable menu system, and Bash integration. More information can be found at the official SpaceFM website.
Or you can useAUR package if you need a GTK+ 2 version.
See the User's Manual.
SpaceFM provides a built-in file search feature similar to:
$ spacefm -f
SpaceFM includes a lightweight desktop manager. . It replaces the desktop menu, adds desktop icons, and sets the wallpaper.
To restore the native window manager menu, open
$ spacefm --desktop-pref
and enable the
Right click shows WM menu option in the
Desktop tab. Consider adding the above command to a keybind and/or the native desktop menu for easy access.
$ spacefm -d
How SpaceFM may be autostarted as a daemon process or to manage the desktop for a standalone window manager will depend on the window manager itself. Should a window manager not provide an autostart file, edit xinitrc or xprofile.
Mounting remote hosts
SpaceFM supports mounting remote hosts via udevil. To add a remote host, add the access URL into the URL bar. A terminal window should pop up showing the mounting process which is useful for error tracing.
An overview of the supported remote hosts is available in the udevil help. For example to mount a remote FTP server:
Tips and tricks
Open archive in app instead of extracting
By default, SpaceFM is configured to extract an archive when double clicking on it. If you instead want to open it with your default archive manager such as, then select an archive, right-click for context menu, and then: Open / Archive default / Open With App
If you have a custom context menu command that should be only shown on selection of files or folders, then add the following rules to
Menu Item Properties -> Context:
MIME Type equals true File Is Dir equals true File Is Text equals true
Columns are not resizeable
This should only happen on the first start of SpaceFM (GTK+ 2 version). 
If SpaceFM crashes with errors such as:
localhost kernel: [245086.687050] spacefm: segfault at 3e8000003e8 ip 00007fc95c586866 sp 00007fffb1dc9cc0 error 4 in libgtk-x11-2.0.so.0.2400.24[7fc95c446000+435000]
SpaceFM uses many different GUI elements, and is thus suspectible to a malfunctioning theme (especially in GTK+ 3). Try a different theme such as Raleigh (default theme). To do so for SpaceFM only, in GTK+ 2:
