One of the field types available in KOTS’ [Config](https://kots.io/reference/v1beta1/config/) Kind is a `file`. This allows the end user to upload the file, and the application is able to consume the contents via our [templating](https://kots.io/reference/template-functions/config-context/).

But, what if you want to check if the file is there at all? In that case you can use the `eq` operator to check the file against an empty string. In the example below, a label is displayed when a file is not uploaded:

```auto
apiVersion: kots.io/v1beta1
kind: Config
metadata:
  name: config-sample
spec:
  groups:
    - name: example_settings
      title: My Example Config
      description: Configuration example to show the file config
      items:
        - name: file
          title: Upload File
          help_text: upload a file
          type: file
        - name: label
          type: label
          title: File Not Uploaded
          when: repl{{ eq (ConfigOption "file") "" }}

```
