When you delete a file, Windows removes the pointer and marks the sectors containing the file’s data as available. Each file and folder on your hard disk has a pointer that tells Windows where the file’s data begins and ends. Windows (and other operating systems) keep track of where files are on a hard drive through “pointers”. This allows you (and other people) to recover files you’ve deleted. When you a delete a file, it isn’t really erased – it continues existing on your hard drive, even after you empty it from the Recycle Bin. So What happens, When you delete any files from your computer or format it?
