When a word file is created, NTFS allocates space to store that file in hard disk. Alongwith this wordfile, metadata is also created, how is this metadata stored ? Is it stored with the file ? If yes, then how come it does not get included in the file size ? File just includes the content size put in the file by the user. As this metadata is system created, if its not included in file size and is stored at a separate place in hard disk, how is it linked with the main file ?
