O&O UnErase will be able to find and restore those deleted files within just a matter of seconds. In almost the blink of an eye, important documents, digital photos, and videos will be back in your hands again. Erased data is marked as “available” on a hard disk or memory card. So even the simple installation or downloading of a data recovery program from the internet can overwrite this data, and all chance of rescuing it are gone. That’s why O&O UnErase should already be installed on your computer before the loss of data occurs, because the speed at which you act is of the essence.
