Hey, the .mdc rules have to live in `.cursor/rules`, as from your file tree, it looks like Cursor is correctly writing them there!

No, I have manually copied data in there. I am not even trying to write rules I am trying to write prds to a prd folder they just happen to be mdc files.

Hey, try adding these settings to Cursor:

```auto
  "workbench.editorAssociations": {
    "*.mdc": "default"
  },
  "files.associations": {
    "*.mdc": "markdown"
  }

```
