I run Lubuntu on my primary machine, but am running Ubuntu on a desktop. I was attempting to set Pcmanfm as the deafult file browser and everything seemed to go well. Using terminal I installed no issue, then I executed the below to set as deault

sudo mv /usr/bin/nautilus /usr/bin/nautilus.bak

sudo ln -s /usr/bin/pcmanfm /usr/bin/nautilus

But now if I click files from the menu bar (on the left side of the screen) nothing happens. What do I need to change so that it will open pcmanfm

Assuming you are talking about the unity launcher, you will need to make a .desktop file to point to pcmanfm.

The relevant ubuntu help is here:

https://help.ubuntu.com/community/UnityLaunchersAndDesktopFiles

Essentially though, I find it easier to copy a working .desktop file from

/usr/share/applications/

to

~/.local/share/applications

and edit it to point to the right place.

The file needs to be of the form:

[Desktop Entry]
Version=x.y
Name=ProgramName
Comment=This is my comment
Exec=/home/alex/Documents/exec.sh
Icon=/home/alex/Pictures/icon.png
Terminal=false
Type=Application
Categories=Utility;Application;

I dont really know if there is a way to achieve that, but I wouldn't recommend to change the default file browser. Tried it onces without luck. Because Nautilus is not only the file browser, but also the desktop etc. If you change it, it will have some unwanted consecuences. If you really want to work with pcmanfm better make a clean lubuntu install, which is based on this file browser. Works great also on older machines.
