Greetings.
I have two questions.
1. Is it possible and how to set icons for files by extensions?
2. Is it possible and how to set what to open files by extensions?
PS. It is by extensions and not by MIME types. For example, there are .txt and .code-workspace files - they have the same type, because just text files, but you need to open them with different applications. An attempt to configure the application through the file property works, but reassigns the application, apparently, by the name of the MIME type, because after I assigned CODE for .code-worspace, and .txt began to open through CODE, and when I set up .txt files, the setting for .code-workspace fell off.
