After deleting files i even emptied them from recycle bin, how do I recover data?

I deleted some important files from Windows Explorer and even emptied them from recycle bin, how do I recover data?

When we delete a file it isn’t actually deleted. After scanning the drive using Disk Doctors NTFS Data Recovery software you should be able to restore it from “Recycler” (Applicable to 2k / XP/ 2k3 only) folder unless the file is overwritten permanently.
