### Context

<a id="context_it5_x1v_v4b"></a>
You can author attachment objects that you can use to store file data and images.

<b>Note:</b> If you delete an attachment object, the object data is no longer accessible. Nobody can access or view the file data or image.

### Steps

1.  <a id="step_N10070_N1006D_N10052_N10001"></a>In App Builder, add an <b>Attachment</b> component.
2.  <a id="step_N10112_N10032_N10028_N10001"></a>Author 1 or more attachment objects for your app. Example using Code mode:

    ```
    {
      "id": 1,
      "name": "CharityImage",
      "label": "Charity Image",
      "defaultSecurityDomains": [
        "ManageCharities"
      ],
      "defaultCollection": {
        "name": "charityImages",
        "label": "All Charity Images"
      },
      "isFilePurgeable": true,
      "fields": [
        {
          "id": 1,

        },
        {
          "id": 2,
          "name": "uploadedDate",
