`ignoreFiles` supports the use of Regular Expressions (RegEx) so you can ignore patterns as well (e.g. ignoring all `.png`s by doing `\\.png$`).
More details in [Hugo's documentation](https://gohugo.io/getting-started/configuration/#ignore-content-and-data-files-when-rendering).
### Global Ignore
However, just adding to the `ignoreFiles` will only prevent the page from being access through Quartz. If you want to prevent the file from being pushed to GitHub (for example if you have a public repository), you need to also add the path to the `.gitignore` file at the root of the repository.
