Nemo is a fork of GNOME Files (formerly known as Nautilus). It is also the default file manager of the Cinnamon desktop. Nemo is based on the Files 3.4 code. It was created as a response to the changes in Files 3.6 which saw features such as type ahead find and split pane view removed.

Set Nemo as default file browser
To set Nemo as the default file browser, execute the following:
$ xdg-mime default nemo.desktop inode/directory application/x-gnome-saved-search
Show / hide desktop icons

$ gsettings set org.nemo.desktop show-desktop-icons false
This fixes the console warning

Change the default terminal emulator for Nemo
is set as the default, if it is not installed, neither the "Open in terminal" context menu entry feature will not work, nor shell scripts or terminal applications won't run from Nemo.
You can change the default setting with
gsettings to the preferred terminal application.
$ gsettings set org.cinnamon.desktop.default-applications.terminal exec <terminal-name>
To be able to run shell scripts from Nemo, make sure you set up the proper argument for the preferred terminal application (the default is
-x for ).
$ gsettings set org.cinnamon.desktop.default-applications.terminal exec-arg <argument>
To useas the default terminal emulator, use the following:
$ gsettings set org.cinnamon.desktop.default-applications.terminal exec urxvt $ gsettings set org.cinnamon.desktop.default-applications.terminal exec-arg -e
Set keyboard shortcut for "Open in terminal"
If you want to edit keyboard shortcuts, you need first to change /org/cinnamon/desktop/interface/can-change-accels respectively /org/gnome/desktop/interface/can-change-accels if you are using Gnome desktop. You can do that with dconf-editor or with this code in terminal:
$ gsettings set org.cinnamon.desktop.interface can-change-accels true
or for Gnome:
$ gsettings set org.gnome.desktop.interface can-change-accels true
Edit or create
~/.gnome2/accels/nemo and add the following line (replacing "F4" with the desired key combination):
(gtk_accel_path "<Actions>/DirViewActions/OpenInTerminal" "F4")
<Shift> can be used as key modifiers (for example,
Tips and tricks
Nemo allows the user to add new entries to the context menu. The file
/usr/share/nemo/actions/sample.nemo_action contains an example of a Nemo action. Directories to place custom action files:
/usr/share/nemo/actions/for system-wide actions
~/.local/share/nemo/actions/for user actions
Action files must have the
.nemo_action file extension.
[Nemo Action] Name=Clam Scan Comment=Clam Scan Exec=gnome-terminal -x sh -c "clamscan -r %F | less" Icon-Name=bug-buddy Selection=Any Extensions=dir;exe;dll;zip;gz;7z;rar;
[Nemo Action] Active=true Name=Archive %N Comment=Archiving %N will add .archive to the object. Exec=<archive.py %F> Selection=S Extensions=any;
#! /usr/bin/python2 -OOt import sys import os import shutil filename = sys.argv print "Running " + filename print "With the following arguments:" for arg in sys.argv: if filename == arg: continue else: print arg #os.rename('%s','%s.archive') % (arg,arg) shutil.move(arg, arg+".archive")
[Nemo Action] Active=true Name=Compare later Comment=Save file for comparison later. Exec=<compare.sh save %F> Icon-Name=meld Selection=S Extensions=any
[Nemo Action] Active=true Name=Compare with saved element Comment=Compare %F saved file or directory. Exec=<compare.sh compare %F> Icon-Name=meld Selection=S Extensions=any

Filenames containing spaces
By default, Nemo does not escape filenames. This means that actions for multiple files with some names containing spaces are broken. To fix this, use
Thumbnail generation errors shown in the console
By default, nemo does not generate thumbnails for certain video files due to licensing or patent problems (AVC encoded mp4 and mkv files for example). As such, you might see errors similar to the following in the console:
CinnamonDesktop-WARNING **: Error creating thumbnail for file:///home/username/video.mp4: Unrecognized image file format
for mp4 and other video files.
To fix this, ensure that you have a thumbnailer for video files installed - see File manager functionality#Thumbnail previews - and also ensure you have the necessary GStreamer packages installed that will allow the video file to be played.

Desktop icons not shown
Since Nemo v3.4.2, the desktop is managed by `nemo-desktop`. This can be configured to auto start by copying the file
~/.config/autostart/nemo-autostart.desktop and removing the line "OnlyShowIn=X-Cinnamon;".
