Correct. It used to be the case that the files were called CURGROUP
and CURSUBGROUP on Cygwin (to prevent clashes with the "group"
folder), and GROUP and SUBGROUP on other systems (which would
presumably have a case-sensitive filesystem).

This was changed back in the 5.3 branch to always use CURGROUP and
CURSUBGROUP. Sample data for 5.3/5.7/6.x should be using the new
names. Sample data for 5.0.x will have to use the old names (because
those are the names which the imagery library uses), and won't work on
systems with case-folding filesystems.
