How to Recover Deleted Files from Hard Drive?

I deleted about 50 pictures that I had stored on Kodak easy share. I also deleted them from the recycle bin. I still have the file names, as the deleted pictures show up as empty albums. Is there way I can recover these files?

Method 1

Firstly, stop writing new data to your PC in case the deleted files were overwritten. Click Recycle bin to check whether the deleted files were there. If so, find out your deleted file and click “Restore this item” on the menu bar. The file will be restored to its previous location.
If you emptied the Recycle Bin or used Shift+Delete to erase the file, the above trick will not work. Yet it also can be recoverable for file and folder are still not really deleted, you just lose the entry in my computer. The content still exists on the hard disk and the space can be available by other files though. If the space isn’t occupied by other files, you can get back files and folders.

Method 2
If you made a backup copy of all your data before deleting a file, maybe you can recover the file from it. Use the function of your backup program to locate and restore a specific file and folder. Windows 7 allows you to recover file and folder with Windows 7 Backup and Restore. Here is the procedure:
Click the Start button, select Control Panel, then System and Maintenance, and finally Backup and Restore.
1. Click the Start button, select Control Panel, then System and Maintenance, and finally Backup and Restore.
2. Click “Restore my files” and follow the steps provided n the wizard to specify which file and folder to recover.

If the above methods failed, you might still be able to recover deleted files and folders using a third party deleted file recovery program like Card Data Recovery. It uses a file and folder signature search algorithm to help you scan the whole hard disk. Small files stored in one cluster or larger files stored in consecutive clusters will be found immediately and recovered quickly. You can preview pictures and audio before recovery. Nevertheless, the pretend is files and folders were not overwritten, or else there is no way to get them back.
