When you delete a file, the OS removes the pointer to that file (akin to erasing page numbers from the table of content of a textbook) and marks the sectors containing the file’s data as available.įrom the file system’s point of view, the file is no longer present on your storage device, and the sectors containing its data are considered free space. It’s a lot like the index page in textbooks. Each file on your device memory or storage has a pointer that tells the OS where the file’s data begins and ends. The operating system (Android, Windows, etc) uses a concept called indexing to keep track of where files are stored in a device. Permanent data erasure goes beyond basic file deletion commands, which only remove direct pointers to the data disk sectors, and make data recovery possible with common software tools.
