Is a Deleted File Really Gone?
Science Fair Project Idea
When you delete a file, by accident or on purpose, is the information really gone? Can you get it back? If you accidentally deleted your five-page report for school, you are hoping it is not gone. On the other hand, if you do not want someone to get their hands on the goofy and unflattering pictures you and your best friend took while staying up late the other night, you probably hope it is gone for good! It might be nice to know for sure either way. Try this project to find out. Read more
