It has been proved that, even if you are the most careful user in the world, you will always lose data from your PC. This could be due to a mistake you make, a deletion by accident or an attack by a virus or other threat.
For these situations it is always useful to have a tool like Easy FAT File Undelete. It lets you recover files (or even whole folders) that have been lost from your hard drive (but it only works with FAT31 and FAT16 systems). The user can establish the search filters to specify which types of file you want to restore.
Easy FAT File Undelete lets you recover files not only from the hard drive but also from Flash cards, and even allows data recovery after the hard drive has been low level formatted.
