If possible, do not save anymore data onto the system after the data in question have been deleted / lost.
Close all applications without saving any data to the disk or other data storage media (if possible).
Switch off the computer.
Think patiently about how data has lost. Try not to panic and quickly restore the data in question as adventurous behavior can lead to even more data loss.
If the data were really lost or deleted then it is advised to use Disk Doctor Data Recovery software to restore them, by attaching the drive to the machine where Disk Doctor Data Recovery software is installed.
