Note: It is recommended to use the application '4DDiG PDF Recovery Tool' in order to make sure only non-vital files are recovered. After the file is recovered, it is recommended to use Photoed, which is a tool to delete photos from your computer's hard drive. It is also recommended checking your drive, since your computer might be overwritten by corrupt or lost files in case you decide to recover the file later.
