Automatic creation of named "icon" files

First, search the help docs and this forum. Maybe your question has been answered! The debugging steps can help, too. Still stuck? Delete this line and proceed.

What I’m trying to do

Every time I create a folder in the sidebar and insert a new note in it, a blank file named “icon” is automatically created in the folder.
When I click on this file, it opens in my computer’s default text editor.
When I read the information on this file (equivalent to looking at the properties on a PC), I just see that its full name is "icon?
What do these “icon” files correspond to?
How can I stop it creating them automatically?
Thank you in advance for your answers.

Things I have tried

Have you tried these steps? This seems like it could be a plugin issue.

Thanks for your repy.
I have just have tried it. Hasn’t solved.

Please open the command palette, run “Show debug info”, and paste the output here.

Opening the command pallet is Cmd+P ?
If yes, when I open it (I’m on a french version), I don’t see any command looking like showing debug info .
What do I have to do to have acces to this debug info ?

The translation file says it’s “Afficher les informations de débogages”.
