Ubuntu – Change filetype icon (Pcmanfm LXDE)

iconsnautiluspcmanfmthunderbird

I've been trying to change the icon for the filetype *.eml (message/rfc822) within PcManFm (file manager of LXDE) but after severall hours and many lines read and tried, I still cannot find a working solution, neither for PcManFm nor for Nautilus.

I have a 48×48 png file called thunderbird.png which I would like to make the image of the *.eml files

I've tried with:

xdg-icon-resource

xdg-icon-resource install --context mimetypes --mode user --size 48 ./thunderbird.png message-rfc822

assoGiate

changed the default icon for the message/rfc822, but it did not changed anything nor in PcManFm nor in Nautilus

and this other solution for Gnome/nautilus

didn't worked also…

Does anyone have a clue/idea of how to solve this?

I'm trying to show a person that everything he does with windows can be done with linux, and he works a lot with email_files.eml that in windows show up with the thunderbird icon…

Cheers

The way of installing icons in Lubuntu is by going to Customize Look and Feel:

enter image description here

And these sets of icons are not file-browser-specific, they would be the same in all file browsers.

As icon sets come as deb files you might try an icon-set that contains the image for your file, extract the deb, replace the file related to what you want with the one you want instead, archive as tar.gz and than replace extension to deb, and install this deb.

But I am afraid I do not know how to do this specifically for the file type you mentioned, because I am not familiar with that file. But you should know more about that.

Also a problem might be the fact that these images in the deb file are svg, not png images.

Instead of trying all this, maybe you should consider that the best way to deal with your friend would be not to show him that Ubuntu can do the same things as Windows, but that it can do a lot more, only differently. For example changing all icons very easily.

Why bother to add single file-type icon when you can get unitary-style icon sets of superior quality?

For example these monochrome ones:

You might find that an icon-set you like will also change the image of the type of file you talk about to something better than you had imagined.

Ubuntu – How to change the icon for a particular file type

Here is a set of instructions that should get you a custom icon for hwp files.

Open a terminal :

Check the MIME type exists : grep 'hwp' /etc/mime.types

if you get an output resembling application/x-hwp hwp skip the next step.
Create the MIME type sudo -H gedit /etc/mime.types and add the line application/x-hwp hwp
Add the icon (which must be called application-x-hwp.svg):
```
sudo cp PathToIcon/application-x-hwp.svg /usr/share/icons/gnome/scalable/mimetypes
```
(don't forget to replace PathToIcon)

Ubuntu – How to make nautilus the default file manager in LXDE

When you open file manager you get

enter image description here Now go to Menu --> Accessories --> File Manager --> right click, and choose properties

enter image description here

Change pcmafm to nautilus and you will get

enter image description here

However that only changes the application that will be opened by the shortcut "file manager". It does not make nautilus the "default file manager" in the proper sense: Opening a folder on the desktop, or opening a file location from an application would not open nautilus, but still pcmanfm.

Note: I will be adding information on how to make this change permanent in the next couple of days.

Note: This is my own personal opinion. I've tried these steps on my machine, and they worked. But I didn't like the outcome.

Change the contents of /etc/xdg/lxsession/LXDE/autostart as shown below.

From

@xscreensaver -no-splash
@setxkbmap -option grp:switch,grp:alt_shift_toggle,grp_led:scroll us,ar
@lxpanel --profile LXDE
@pcmanfm --desktop --profile LXDE 
@/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1

@xscreensaver -no-splash
@setxkbmap -option grp:switch,grp:alt_shift_toggle,grp_led:scroll us,ar
@lxpanel --profile LXDE
@/usr/bin/nautilus -n
@/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1

Also you can take a look at https://help.ubuntu.com/community/DefaultFileManager to see if it might help.

Edit:

In Ubuntu 14.04 here's what I did. I did a fresh installation of Ubuntu 14.04, and then installed LXDE. Once that was done, I set nautilus as a default file manager using the following command:

xdg-mime default nautilus.desktop inode/directory application/x-gnome-saved-search

and then I checked the current default file manager using the command below:

xdg-mime query default inode/directory

and it showed Nautilus as the default. See image below.
