Generally whenever you delete a file from your computer, its moved to the Recycle Bin , which when deleted makes sure that the file is completely deleted, but this is wrong because the file is still loaded in your hard drive which is replaced whenever some other files are added to the hard disk. Instead of getting into larger drives lets take a example of a 128 Mb Memory Card, where in if you have take some photos and then deleted them you would feel that the card is empty but that’s just the software which shows this information, in real the data is still available and which can be recovered using data recovery programs.
