It is quite easy for users to delete files into the trash on Mac and most Mac users would clean up their trash bin regularly. However, sometimes this can cause serious data loss issues when users realize that they deleted some important files and emptied Mac trash without awareness.
Clicking "Empty Trash", in fact, does not mean to erase the files in the trash bin but instead the hard drive's directory entries for those files. This means those deleted files are still at somewhere on the hard disk and you can't see them with your naked-eyes. You can recover them as long as OS X has not re-used the directory and cataloged the information.

And of course, no further operations shall be done to the Mac trash.
