# MIME-Types

{% hint style="warning" %}
Currently we have not yet loaded the MIME-Types on our contracts. Once that feature will be enabled, the MIME-Type list below will be updated. So far the only MIME-Type accepted is "0" (unknown value)
{% endhint %}

While the official list of MIME-Types can be found [at this link](https://www.iana.org/assignments/media-types/media-types.xhtml), we will initially support just a portion of them, to cover the most used cases. If your MIME-Type is not supported, or it is not available, the value 0 is to represent an unknown MIME-Type.

The MIME-Types are stored as *uint32* values, and can be set only if a public file URL has been set.

If you want to add a custom MIME-Type that is needed within your project, don't hesitate to contact us!

### Supported MIME-Types
