>>2) REINDEX (except in VFP7SP1) will remove CDX "bloat" of both the deleted TAG variety and the 'random inserts causing extra nodes' variety. A smaller file is always better and I should think especially so where it is a .CDX. A REINDEX will also result in a 'contiguous' (as much as available RAM will allow) .CDX file as its output.

Well I'd like to know how you can conclude that with the evidence at hand. I have shown that a VFP7SP1 REINDEX does not shrink the CDX, nor grow it (by any more than 512 bytes and only in some cases).
In this case, how can you be so sure that "bloat" is removed???? Specifically the "insertion" variety.
