The most common method to delete files in Windows operating system is to drag the file into recycling bin. While that removes it from the desktop but does not remove it from your personal computer. You can restore the deleted file by simply opening the recycle bin and dragging it back to the desktop. You can even empty the recycle bin to delete the files completely but this method does not delete the files permanently. Even formatting or reformatting the disk also does not delete the data completely. Erasing a file does not actually delete the data but only the pointer referring to those files get deleted.
