When you right click a file and press Delete button, the system just hides the data by removing its file directory and mark the space as free for use. At this moment, you can easily get back the file back by rebuilding the file directory. But if you continue to use the device, it might write some new data and completely erased the contents of the old deleted files. In this case, the chance of a successful data recovery is decreased. The situation can become much more terrible when you have a hard drive, memory card or USB drive with a limited free space.
