ruby on rails 3 - Uploadify - How to upload contents of a folder recursively -

I have to upload files in a folder recursively

in the folder Is it possible to use uploads to upload folder contents by choosing a folder instead of selecting individual files?

I do not think so. Browser is in the control of file selection dialog (which will not allow you to select folders, only files).

I paid the Uploadifive (HTML 5 edition), but it can support dragging a folder. Not sure how HTML5 allows drag-drop
