NTFS Data Recovery Toolkit (formerly called NTFS Recovery Toolkit, and NTFS Data Recovery for short) is a set of tools (Disk Editor, Partition Manager, Partition Recovery and File Recovery) that mainly used to analyze and recovery the problem and files on NTFS disk partitions. It supports both 'Manual' and 'Automated' modes to recover data that has been accidentally deleted or lost.

On hard disk, when you delete some folders, files or even an entire partition, all data is still existing in the same place where it was, and will always be there until overwritten. In fact, the deleting operation is just delete the pointer to the data on disk from MFT (Master File Table), so as to allow the operating system to perform writing operation there. Any data recovery software use this principle to work. Of course, you can delete the data truly and completely. But that requires you to ask special data eraser for help.
