# File

Use a **File** field when users should upload or attach files to a record.

For the general settings all data fields have in common, see [Shared field settings](/builder-hub/design-your-app/add-and-edit-data-fields-in-your-tables/all-data-fields/shared-field-settings.md).

Field-specific settings for **File** are:

<i class="fa-airplay">:airplay:</i> **Display**

* **Display as**: controls how the file field appears on the form
  * **Thumbnail**: shows the file as a thumbnail, this is the default setting
  * **Preview**: shows a larger preview in the form
* **Metadata**: controls whether metadata such as the file name, size, and type is shown

On the form, users can click **Browse files** to add a file. After they add a file, the field reflects the selected settings.\
Users can click **`⋮`** to **View**, **Download**, **Replace**, or **Remove** the file.

Ninox also stores the file in **Files**, where users can access it later. If you remove the file from the field, it remains available in the record’s linked **Files**. There, users can **Download**, **Rename**, **Unlink**, or **Move to Trash**. For more information about file storage, see [Documents](/user-hub/ninox-basics/documents.md).

{% hint style="info" %}
Use **File** when the record should store attachments. If you only need a link to an external resource, use **URL** instead.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ninox.com/builder-hub/design-your-app/add-and-edit-data-fields-in-your-tables/all-data-fields/file.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
