# Folder Extension CRUD Actions

## Overview

Folder Extensions create a Folder that acts as an Entity. The Folder behaves like other Portal Folders in that it allows actions to be performed on each Entity in the Folder and the Folder can be used in Reports.

CRUD Action Steps: Folder ExtensionIn the Flow Designer's Toolbox, **Create**, **Update**, and **Delete**steps cannot be searched for. Users will have to navigate to **USER DEFINED TYPES > FOLDER EXTENSION** to add CRUD actions to the workspace.

## [Prerequisite](/v9/docs/creating-folder-extension-data-structures)

The following tutorial uses a Database Structure called "Person_FE" with the following attributes:

| Person_FE |
| --- |
| Data Member | Data Type |
| Name | String |
| Gender | String |

## 

## Create

Folder Extensions store data, however, users will have to create a Normal Folder to store the process data. In this example, a normal Folder called Person_FE Data was created.

Do Not Store Data In The Configuration FolderData Structures that are a part of the Decisions Entity Framework will automatically have a Configuration Folder. Do not store data within that Folder. The Configuration Folder is meant for creating Flows, Rules, and other Designer elements to enhance that custom Data Structure. For more information, please navigate to the [Configuration Folder](https://documentation.decisions.com/docs/configuration-folder) article.

1. In a Designer Project, click CREATE FLOW to [create a new Flow](/v9/docs/creating-your-first-flow-2).
2. In the **Toolbox**panel, navigate to **USER DEFINED TYPES > FOLDER EXTENSIONS > PERSON_FE** and connect the **Create Person_FE** step to the **Start**and **End**steps.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/image-1750788780149.png)
3. On the**Properties**panel, set the mapping of the **Extension Data** field to **Build Data.**Enter in **Constant**values for the data fields **Gender**and **Name**.Auto-ID GenerationThe ID will automatically be created when the Flow runs, even though its input mapping was set to Ignore.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/image-1750788892465.png)
4. Set the **Folder Description** and **Folder Name** fields to Constant mapping and enter values. Set the **Parent Folder ID** mapping to Constant and click PICK. Select the folder **Person_FE Data** and click PICK.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/image-1750789074505.png)
5. Click **Save**to save changes to the Flow.
6. On the top action bar, click **Debug**.
7. Click START DEBUGGING. This will open the Debugger and create a record in the Folder Extension Structure.

### Update

To update an existing record in a Folder Extension Data Structure, use the **Edit**step. The Edit step will change every data field in the object, even if only one data field has been changed. The **Fetch Entities**step will be required to fetch a particular record and will pass the Id of the record to be changed into the Edit step.

If the Edit step is used to change one field, that field will update with the new value, and all unchanged fields will be set to Null or Empty.

### Delete

To remove records from a Data Structure, use the **Delete**step. This step will expect an **Id**as an input to delete that record from the Folder Extension Data Structures.
