The older w98 systems can't work with NTFS, and one still has the wasted space in the MFT. FAT32 is much more efficient for large files in this case. It seems I have to uncompress everything from a 7z spanned archive. It isn't so much compression level, which was medium, but 50GB is 50GB, and over USB... In retrospect, 4GB is probably too big for any method.
