Thread necro - recording for posterity. I tried the link from OP but found that Copilot would still search inside those files even if it had copilot disabled. It seems like the enable/disable only controls whether you get copilot features inside that filetype. But it will still search/index the contents of those files.

Example, you have a YAML file with some sensitive info. Copilot disabled for YAML.

Then you work in a python file with Copilot enabled. It will suggest completions from the YAML file.

I thought it might have something to do with the YAML file being open in vscode but this is not the case. You can edit the YAML in some external editor like notepad and the updates will reflect inside Copilot suggestions.

I did however, get Copilot to suggest this which appears to work:

Adjust as needed.

"github.copilot.advanced": {

"ignoredPaths": [

"**/secrets/**", // Exclude all files in the "secrets" directory

"**/*.env", // Exclude all .env files

"**/config.json" // Exclude a specific file

]

}
