You can choose to compress a dictionary
completely, or to remove only unused blocks of space from a
dictionary:
Total Compression - Mark this option if
you want to create the smallest version of a dictionary for
distribution. All script source will be removed, as well as any
unused blocks and unused space within blocks.
Remove Unused Blocks - Mark this option if
you want to remove only empty blocks of space in the dictionary.
This is useful if many resources, especially large ones like
pictures, have been removed from a dictionary.
