For car nef files, there is a *.ctf file in the archive. This file does not have any part 4 data (its p4 index is -1). But the extracted size listed in the part 1 entry is always 8 bytes short. This was confirmed by looking at the diffs between an original nefs archive and an archive saved by NeFSEdit. For now, we are just manually adding the 8 bytes in NefsWriter.cs.
if (item.CompressedSize == item.ExtractedSize
&& item.ExtractedSize != 1
&& item.Part6Unknown0x02 != 3)
{
// Add 8 bytes to the size for some reason
srcSize += 0x8;
}
The last item in the archives are 1 byte long (and have a -1 part 4 entry) but their size is actually 1 byte, so this doesn't apply to those items.
