# Cases settings in Kibana
You do not need to configure any additional settings to use [cases](https://www.elastic.co/docs/explore-analyze/alerts-cases/cases) in Kibana. To provide greater control over case features, you can configure the following settings in the `kibana.yml` file:

## Cases settings
<definitions>
  <definition term="xpack.cases.files.allowedMimeTypes">
    <supported-on>Elastic Cloud Hosted: Generally available, Self-managed Elastic deployments: Generally available</supported-on>

The MIME types that you can attach to a case, represented in an array of strings. For example: `['image/tiff','text/csv','application/zip'].` The default MIME types are specified in [mime_types.ts](https://github.com/elastic/kibana/blob/master/x-pack/platform/plugins/shared/cases/common/constants/mime_types.ts).
Datatype: `string`
  </definition>
  <definition term="xpack.cases.files.maxSize">
    <supported-on>Elastic Cloud Hosted: Generally available, Self-managed Elastic deployments: Generally available</supported-on>

The size limit for files that you can attach to a case, represented as the number of bytes. By default, the limit is 10 MiB for images and 100 MiB for all other MIME types. If you specify a value for this setting, it affects all file types.
Datatype: `int`
  </definition>
</definitions>
