How Files are Deleted in MS Windows
When a file is deleted, it is not permanently removed from the hard drive until another file overwrites the occupied space.
Since a single file can span multiple locations on your hard drive, it can be 'partially' overwritten by other files. In techy terms, this is referred to as file fragmentation.
