You are right that there are two items (#'s 27 & 28) still on
the SIGIMAGE Enhancement list in this area. But they deal
with files that are or might be associated with a particular
IMAGE database like the schema, tool-specific data files, etc.
IMAGE B-Tree HFS files are integral parts of the database
itself (just like JUMBO details), which at least in my book is
a completely different deal than "associated files".
Since B-Trees can always be re-created by re-INDEXING, I
might buy an option to not have VSTORE check for them if
there was enough call for that feature. But IMO there is no
doubt default should be to include B-Trees if they are present,
in whatever integrity checking TurboSTORE / VSTORE might
do. And going on the theory that it's best to avoid proliferating
options unless necessary; and the projection that B-Trees
will in most cases make up <= five percent of the total space
taken up by the database (ours take < three percent); think
I will try and maintain that VSTORE ignoring the absence of
B-Trees that should be there when it checks for JUMBOs
and other datasets is a defect....
