You need to use a file recovery application that has been exclusively developed for such operations and luckily, there are plenty to choose from. For example, Recuva is one application that is free and has good accuracy when you want to retrieve something that has been deleted.
Access the following page to download it and then use the built-in Wizard to configure the scanning procedure. For improved accuracy, but with more time scanning, choose Deep Scan and also provide the installation directory of the files you want to recover.
