Upload Queue

When a file gets added to the dropzone, its status gets set to Dropzone.QUEUED(after the accept function check passes) which means that the file is now in the queue.

If you have the option autoProcessQueue set to true then the queue is immediately processed, after a file is dropped or an upload finished, by calling.processQueue() which checks how many files are currently uploading, and if it’s less than options.parallelUploads, .processFile(file) is called.

If you set autoProcessQueue to false, then .processQueue() is never called implicitly. This means that you have to call it yourself when you want to upload all files currently queued.
