No, it does not allocate a fixed 8K (or 32K) block per row. The size of a row is dependent on the data stored within the row. Each row also contains a header of modest length. - Don Baccus, Portland OR <dhogaza@pacifier.com> Nature photos, on-line guides, Pacific Northwest Rare Bird Alert Service and other goodies at http://donb.photo.net.
