Describe the bug

A clear and concise description of what the bug is.

When creating a new record, we try to upload a folder with subfolders using 'drag and drop'. The folder and subfolder structure is not preserved.

Steps to Reproduce

1. Go to '...' https://127.0.0.1/uploads/new
2. Drag and Drop a folder with subfolders Original folder-structure:

3.See error

After drag and drop:

Saved and published record:

Expected behavior

• It would be great, that folders and subfolders can be uploaded and not only files all on one level.
• Obliviously, you could upload a zip-instead, but then we do have the folder-structure as preview and cannot preview the files.
• If uploading folders is not possible (as it is currently the case with the 'Uploads files' Button / Window) the drag-and-drop should give me a warning or disable me from doing it completely and not just catching some files - we guess it just gets the files in the first sub directory.

Moved to product board as it's a bigger feature that also involves deciding if we allow upload of folders
