How do you do your saving and loading kartoffel?

In the manual it says: A single var is 4 bytes. So if i did this:

var Max_Nodes[999999];

Its 4 bytes multiplied by 999999, which gives me 3999996 bytes, which equates to 3.999996 megs. So this single array currently would take up 4 megs of space/memory.

So if I use SV_VARS, it will save every array, and I have multiples of these huge arrays. Is this the reason why my .sav file is 20 megs?

I have 60 of these huge empty arrays. If each of them is 4 megs, the total should be 244 megs. Why isnt the .sav file over 244 megs?
