Hi,
My name is Jin. Let's talk about your project.
1. You require drag and drop UI for the 4 REST based APIs for folder management.
2. Your description is quite detailed. I am assuming that the page will have a list/array of folders and image files to start with.
3. I recently did a drag & drop quizzes using JSON file as the source for questions and answers.

What you require is similar.

6. Here are some recent and related projects:
