Added: It's now possible to drag and drop files and folders from desktop (or file system) directly to FileManager.This means you no longer need to open "Upload Files" window first to drop and upload. It works same as internal drag and drop,i.e. you can drag and drop to any folder (or zip file) UI item you see in the FileManager. For example dragging and holdingon a folder node in the folder tree (left pane) will expand the folder node so you can drill down before dropping.While dragging, "Upload to " indicator will display below the cursor to let you know where you are exactly uploading to(subfolder name or not allowed indicator).Dropping folders is supported on recent browsers (Chrome, Firefox, Edge) and IE10+ supports only dropping files but not folders(a warning message is displayed when you drop a folder on IE).Regular "Upload Files" window also supports dropping folders on supported browsers now.
