You ever been an MVS person ?  Used partitioned data sets ? ? ?

OK, TSM will do a trick where it bundles a lot of little files in a big file
within ~TSM space~.

OH, look at it like a ZIP file

so if a bunch of little files are in this one big file that TSM is dealing
with, natrually some files will expire before others...

RECONSTRUCT will do just that to these AGGREGATE (like zip) files and purge
out the expired data when it moves it during reclamation (or during move
data now I see...) ie, it reconstructs it without the old/expired data
