Since expanding a large gzip file takes quite long time (sometimes over half a minute), I'd like to know the expanded size before I start the expansion (for progression report purpose). Is there a way of knowing it without actually expanding? Update: For file larger than 4G bytes (expanded size), there's no sure way of knowing the size...
