Actually, "Deleting" a file doesn’t really delete it. The delete file will be marked as available to be used by system. This means that even if you can’t reclaim it from recycle bin, you can still undelete it with a third-party Windows 7 undelete program before it’s overwritten by new data on your computer.
Attention: Deleted files in Windows 7 can be easily overwritten by new data on your computer. You’d better stop using your computer since files are lost and install this Windows 7 undelete software on another partition/drive on your computer.
Chances of undeleting Windows 7 files are decent as long as you stop using your Windows 7 computer immediately after deleting it. Recoverit data recovery is one of the best Windows 7 undelete programs that you can get from the Internet. It’s able to undelete all kinds of files in Windows 7 with a safe and easy-to-use way, such as photos, videos, audio files, emails, documents, etc.

Select the partition/drive that you’re about to undelete files from and click "Start" to begin scanning for deleted files.
Recoverit will start an all-around scan. Usually, it will take a few minutes to finish the scanning. Sometimes, a few hours are required if many large-sized files are present.
After scanning, all found contents on your Windows 7 partition/drive will be displayed in the program window. You can view file names or preview found images to check how many of your deleted files can be undeleted.
