You accidentally hit the delete or reformat button and all your digital photos are gone. Or memory/disk is corrupted. We save your photos! If it seems like magic, it's not. Data recovery is a science that takes advantage of the way file systems store files. File systems use some form of a master index or table that stores the location of each file on the drive. This makes it possible for programs and operating systems to find the files. When a file is deleted, the file itself remains while the record in the master table or index is deleted. For most purposes, the file is inaccessible unless you have data recovery software that goes past the index and retrieves the file itself.
