File

What it does

This class handles file upload operations for EAV (Entity-Attribute-Value) attributes in Magento 2.

Developers use it when working with custom entity attributes that store files, providing validation, extraction from requests, file upload handling, and deletion of uploaded files.

It's particularly useful when creating custom modules that need file upload functionality for customer attributes, product attributes, or other EAV entities.
