How to change the icons for a specific file extension?

[luizmac]

Hi!

How can I change the icons for all files with same extension? Is there an easy way to do this? I only found how to change for one selected file each time but not for all.

Best Regards.

Hi. Thanks for the answer.

However, this solution is complicated. I've tried some forum solutions and they don't work. So, I came here to know if there is something easier. Does someone know a direct way to do this?

The solution in that link looks complicated because the OP there wanted to set up an icon for a file type that is not known by the Linux system beforehand.

If your target is a file type that is already provided a file type icon in Linux Mint, then the procedure will be simpler. If you want a detailed guide, you will need to provide more specifics of your situation.

Thanks for the comments.

What I want is to replace the Icon of the tex files in my computer with the icon of my selected default application.

I want to change from this

to this

But I want to replace for all files at same time. The file type is "Text (text/x-tex)". Could you help me?

It looks like you are using a variant of Yaru icon theme. What you need to override is the text-x-tex.png.

Here's what I tested and looks working in VM:

sudo find /usr/share/icons/Yaru -path '*/mimetypes/text-x-tex.png' -delete
sudo cp /usr/share/icons/hicolor/scalable/apps/texstudio.svg /usr/share/icons/Yaru/scalable/mimetypes/text-x-tex.svg
sudo gtk-update-icon-cache /usr/share/icons/Yaru

The command above assumed you installed TeXstudio as a "system package". If not, you may install it temporarily to fetch the SVG icon.

Warning: In the command above I deleted the original TeX file type icons from the Yaru icon theme directly. You may consider backup the /usr/share/icons/Yaru folder first before running the command.
