File

What it does

This class handles file uploads in Magento 2's design configuration system, specifically for theme-related assets.

Developers use this as a backend model for configuration fields that accept file uploads, managing the upload process, validation, file storage, and URL generation.

It extends the base file backend model to provide specialized handling for design configuration files like logos, favicons, or other theme assets.
