I read that if any corruption occurs, slim chances of recovering for 2003
version files. In 2007 you can recover almost fully because the actual file
is in zip format and inside it contains many xml files. But the "file" as
such, .docx is a single file (until unzipped & extracted). Then how can some
corruption save the file, because even in a zip format file, if a small
chunk is gone, you can never open it. Could anyone shed some light on this?
Thanks
