  Photorec :

 Photorec to recover the Deleted file.

           It is the fastest utility of the three .You will find the photorec utility under the package of testdisk utility. If you don't want to mess with too much of commands , then this utility is the best for you. All you need is to type the photorec as root in the terminal/terminator .

           Select the device on which you want to operate the search operation and then it will ask you for the partition table type. Select according to yours . In my case its Intel . As soon as you select the option, it will ask you to select the file system or partition of the device disk. Then it will prompt you to the filesystem selection screen.


             * indicates the mounted partition. Select the appropriate file system. Then in the end it will ask you for the folder where you want to restore the deleted files. After selection press y to proceed. Although utilities are there to recover your file I would recommend you guys to keep a habit of using plain old delete and not “Shift+Del” because prevention is always better than cure :D:D
