Please include more details. What do you expect to happen? You can change file type associations with the files.associations setting.

I understand the setting. I just think the default behavior is incorrect. I expect *.config to report as plaintext files.

For instance, my maven.config is reported to extensions as an XML file, but it is just a plaintext file, so it causes Red Hat's XML extension to produce an error. Can you provide reasoning as to why *.config files are XML files by default?
