# SaveImageDataSetToFolder - ComfyUI Built-in Node Documentation

> Complete documentation for the SaveImageDataSetToFolder node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node saves a list of images to a specified folder within ComfyUI's output directory. It takes multiple images as input and writes them to disk with a customizable filename prefix.

## Inputs

| Parameter         | Description                                                                                     | Data Type | Required | Range |
| ----------------- | ----------------------------------------------------------------------------------------------- | --------- | -------- | ----- |
| `images`          | List of images to save.                                                                         | IMAGE     | Yes      | N/A   |
| `folder_name`     | Name of the folder to save images to (inside output directory). The default value is "dataset". | STRING    | No       | N/A   |
| `filename_prefix` | Prefix for saved image filenames. The default value is "image".                                 | STRING    | No       | N/A   |

**Note:** The `images` input is a list, meaning it can receive and process multiple images at once. The `folder_name` and `filename_prefix` parameters are scalar values; if a list is connected, only the first value from that list will be used.

## Outputs

This node does not have any outputs. It is an output node that performs a save operation to the filesystem.
