 But of course, the data is NOT purged, the file size is NOT reduced!
 The data is simply rendered inaccessible to you.  Does anyone know
 what use to make of such settings as "Number of Tick Days to Save"
 and why one would set it to less than one's tick-datafile-crunch-
 copy/paste-procedure interval?  This "feature" has always struck me
 as one of Omega's cruelest hoaxes.  Am I missing something here?

What I usually do with TS4 (copying to te offline machine the latest data
exported from the online machine) does the purge because:

1)I only add historical data from an OMZ file to the offline machine.
The size grows "normally".

 2)I delete the online database and reimport the SAME omz file into the online
machine
Means stat I restart the online machine with the minimum of necessary data.
