Sorry, I don't really have a good answer for you.

>yes, of course I know that indexes can become corrupt; issuing REINDEX in that situation would definitely affect the size of the CDX. My question is whether or not REINDEXing a NON-CORRUPTED index (i.e. one that is otherwise perfectly fine) MIGHT result in a smaller CDX file. Or, is it necessarily the case that a change in the CDX size after REINDEXing indicates a problem with the index.

>>>I noticed that when I issued REINDEX on a few tables (which had not been REINDEXed for quite some time) the SIZE of the CDX file became considerably smaller. Does REINDEX do some kind of optimization that would result in this as a matter of course or might the change indicate a problem of some kind? I can't seem to find any technical reference in MSDN that explains this.
