No, "cannot cast"  so...

typedef union uFT264{
	FILETIME	ft;
	DWORDLONG	i64;
}FT264;

Won't let me cast that either, so copy it.
	FT264	fti,ftj;
	fti.ft = CRCRecord[i].time;
	ftj.ft = fblk->ftCreationTime;
	if(	(CRCRecord[i].Size != fblk->nFileSizeLow) ||
		( fti.i64 != ftj.i64 ) )
	{	/* it's changed! */
	};

Same result as CompareTime.
I had partially run the old code.
The new code compared favorably with the files read on Sunday, but
continued to reject files that were ok Friday.

It really looks like FindFirst/NextFile returns a DST compensated
time.
I'll keep the union. I don't like copying the data, but the compare is
inline, which I _do_ like.

I'll try saving a converted time:
LocalFileTimeToFileTime(&fblk->ftCreationTime, &CRCRecord[i].time );
and see what happens.....

	Nope.
Changed date to March, rebooted, ran the above line, it said
everything changed (ok, first time you'd expect that). Ran it again,
said nothing changed (so far so good). Changed date back to now, ran
this
	fti.ft = CRCRecord[i].time;
	LocalFileTimeToFileTime( &fblk->ftCreationTime, &ftj.ft );
	//ftj.ft = fblk->ftCreationTime;
	if(	(CRCRecord[i].Size != fblk->nFileSizeLow) ||
		( fti.i64 != ftj.i64 ) )
	{
	and it still changed. Also seems slower.

The original code was
FileNotFoundInCrcRecord:
	CRCRecord[CRCOpened].Size = fblk.nFileSizeLow;
	CRCRecord[CRCOpened].time = fblk.ftCreationTime;
NoMoreFiles:
	WriteFile(h,&CRCRecord[0],j*sizeof(crcrecord),&written,NULL);
FilenameFoundInCrcRecord:
	if(	(CRCRecord[i].Size != fblk->nFileSizeLow) ||

(CompareFileTime(&CRCRecord[i].time,&fblk->ftCreationTime)!=0))
	{	return FileNotFoundInCrcRecord;

Takes a couple hours to recalc all the crcs. That's why I keep a db
and first check the size/date/time and only calc those that changed.
The files don't get modified, so creation time is good enough.

More tests to follow....
