A set is a collection of one or more trait folders and each trait folder contains multiple attributes, which helps distinguish the traits further.

Note: (Only png file formats are supported by the tool)

A set allows you to define and pair the desired attributes of your NFT collection based on their attributes.&#x20;

Attributes such as:

**Set Title/Name/Label**: A private name for internal use that helps you refer to the pair of certain attributes.
