Because its value may only be set by a user and not programmatically, an input type="file" /> is always an uncontrolled component in React. To interface with the files, you should utilise the File API.

When utilising an uncontrolled component, the value of the input is only accessible when the form is submitted. When utilising a controlled component, on the other hand, we always have access to the value. As a result, it's simple to add validation tests to each keystroke.
