>very nice little analysis! but what do you do with it? i have a inventory dbf (by far not at 2GB), but if i see, that a field is used only to, let's say 25 %, what do you do with it? i can't leave the field out, it's needed, so i don't realy have a choice, do I?!

Sure, you can store it in an auxiliary table that's linked to the original table using the PK. The analysis lets you figure out whether that will actually save any significant space.
