Hi Orlando,

IB still does the garbage collection but it doesn't give the disk space back
to the OS because allocating new space when new records have to be written
is very time consuming. So after a sweep the not needed disk space isn't
released but reserved by IB for later use.
You still can do a backup and restore over the database to get the initial
size of the .gdb file.

HTH,
Markus
