to compress or not to compress?

Good heavens above DABhand.
I suggest you had better write an email quickly to Microsoft and point out their error.
Obviously, according to you, when they refer to Maximum file size they have it wrong, and they are in fact meaning 'largest block size'.
(Just quietly though I do think they know what they mean)
(Oh yes, this all came about because you insisted that - Quote "NTFS can handle files upto 4gig" - you were wrong about that. It seems you don't want to admit your error)
