Hi Tom, > I suspect that what we really want here is a completely different > algorithm (viz copy into a new file, like CLUSTER) when the initial scan > reveals that there's more than X percent of free space in the file. Yes! Sorry Tom, I missed the detail of this the first time around. However from the figures here it would need to be a very small percentage of free space, perhaps only upto 10-15% where the existing vacuum would be a better method. Hope they were useful to you.
