Delete Action for Dropzone
This action can be added to Dropzone for Mac (https://aptonic.com/).
When dragging any number of files or folders to this action, the dragged items are deleted right after a dialogue (for safety reasons). No moving to recycle bin, no need to empty it.
Download the latest version, unzip it and simply click on the Dropzone action named "Delete.dzbundle". If you have Dropzone installed, the action should be added there automatically. Choose "add to grid" to have it up and running immediately.
