Whatever is stored in your hard disk like file has index number through which hard disk search that particular file. When you delete any file then what happened that the link between the index and the file disappear that mean this file is not going to be in use further and the space taken by that file can be overwritten by you. But one thing keep in mind that deleted file remains on the computer. Only when it is overwritten do you begin to be safe. Even then, a specialist might be able to recover the old data.
