 9Zed will not attempt to format diff files and has [`remove_trailing_whitespace_on_save`](https://zed.dev/docs/configuring-zed#remove-trailing-whitespace-on-save) and [`ensure-final-newline-on-save`](https://zed.dev/docs/configuring-zed#ensure-final-newline-on-save) set to false.

11Zed will automatically recognize files with `patch` and `diff` extensions as Diff files. To recognize other extensions, add them to `file_types` in your Zed settings.json:

13```json [settings]
14  "file_types": {
15    "Diff": ["dif"]
16  },
