The database of 5714925 CF ODLS is:
1.2 GiB when not encoded
142MiB when encoded as names (namer.exe)
99 MiB when encoded binary (my program)

Bytes per Square in different encoding
plain text (format 1 or 2): 222 Bytes
names (format 3): 26 Bytes
binary: 18 Bytes

The binary format is my format. I based it on Belyshev namer.exe. It takes the intermediate "name" and encodes it using 1-0, 3-1, 1-2, 1-2, 1-2, 1-2, 1-1, 1-8 encoding.
