Recuva recovers files deleted from your Windows computer, Recycle Bin, digital camera card, or MP3 player. And it's free! Go to Google search Recuva
Indeed, Recuva is decent, but if you have files with filesize over 4gb, it wont read those files. that happens to me recently & only R-studio was able to recover files over 4gb on NTFS.
Sorry to hear thatyou have deleted some of your files, we have all done this at sine stage in our lives, the best i have used is: EASEUS Data Recovery Wizard Professional
