# Load File

### Overview

The **Load File Component** reads a file stored in the system using its unique file ID and sends its content to the output port. It is useful for processing stored files in workflows.

### Usage

This component is used to retrieve file content for further processing or validation in workflows.

#### Properties

| Property | Type     | Description                                     |
| -------- | -------- | ----------------------------------------------- |
| `fileId` | `string` | The unique identifier of the file to be loaded. |

#### Input Ports

| Port | Description                     |
| ---- | ------------------------------- |
| `in` | Accepts the file ID to be read. |

#### Output Ports

| Port      | Description                           |
| --------- | ------------------------------------- |
| `content` | Emits the file’s content as a string. |

#### Processing Logic

1. **Receives Input Data**:
   * Accepts a `fileId` that identifies the stored file.
2. **Reads File Content**:
   * Opens a stream to read the file contents.
   * Accumulates the content as data chunks arrive.
3. **Sends File Content**:
   * Emits the full file content to the `content` output port.
   * If an error occurs (e.g., file not found), it is logged or raised appropriately.

#### Output Data Schema

| Property  | Type     | Description                              |
| --------- | -------- | ---------------------------------------- |
| `content` | `string` | The complete content of the loaded file. |

### Notes

* **Retrieves Full File Content**: Useful for workflows requiring file content processing.
* **Supports Various File Types**: Works with text-based and structured data files.
* **Ideal for Data Processing Workflows**: Enables automated retrieval of stored files for further actions.

This component is essential for workflows that require accessing and processing stored file content dynamically.
