# Organizing datasets

You can create a hierarchy within your Project to better organize your datasets by creating folders.

## Create a folder

1. Select **New** and choose `Create folder`.
2. Provide a desired name.

{% hint style="info" %}
We support unlimited levels of the hierarchy so you can create as many folders as needed.
{% endhint %}

## Move images between folders

You can move an existing image or images to a different folder using the `Move to` menu.

## Delete images or folders

You can delete existing images or folders using the `Delete` menu, however make sure you are certain about the action as it cannot be reversed. 

{% hint style="warning" %}
Deleting a folder deletes all images included in the folder including sub-folders.
{% endhint %}
