This little software is very useful. Many friends often encounter such a situation: they need to move/copy the files in the current folder to the folder that is covered behind, so they have to separate the two folders first, or open the target folder to paste separately, which is quite troublesome. With this little software, you just need to drag the file and can directly flip the page that is blocking in front to the folder behind~ The video is here: http://liihs.irit.fr/dragice/foldndrop/foldndrop_low.avi
