We would like to implement a feature that allows users to upload entire folders, ensuring that the folder structure is automatically adopted into the platform. This means that folders and subfolders should be seamlessly mapped into Projects or Collections upon upload.

Key requirements:

1. The folder hierarchy must be retained and translated directly into Projects or Collections.
2. Users should be able to upload folders via drag-and-drop or through a file picker interface.
3. Compatibility should include macOS Finder, Windows Explorer, and other commonly used file management systems.
4. If possible, include a preview or confirmation step to verify the structure before the upload is finalized.

This feature should integrate smoothly into the existing workflow and maintain the platform’s intuitive user experience.
