Hello, Otis. There is a big difference when you use compound index format or multiple files. I have tested it on the big index (45 Gb). When I used compound file then optimize takes 3 times more space, b/c *.cfs needs to be unpacked.
Now I do use non compound file format. It needs like twice as much disk space. OG> Have you tried using the multifile index format?
