Setting or unsetting it doesn't change the produced Data.fs.pack (it has the same md5sum). Anyway the pack time considerably reduces (from 4 hours to 25 minutes). > If you think the code is doing something wrong and you would like to try > packing anyway, I would suggest you just comment the entire if in the > fspack.py code and try running this version.
