Last week, I was with my colleagues on our lunch break at work, when my phone rang. My father called me and told me that he'd been having some problems with his laptop, so he asked me to come over to his place after work. When I went to his place, he told me that he had deleted some files by mistake and asked me if there was any way that he could get them back. I decided to browse the Internet and I found this great video that explains how to recover deleted files. I didn't think it was possible, but I retrieved my dad's files.
