PFO is not an archive or distribution format like ZIP, ISO, CFS, 7Z, or RAR. PFO is a full file system like NTFS, EXT2, or FAT32. Compared to archive formats, file systems have additional overhead for allocation management and fault tolerence. PFO uses ZIP (deflate) compression. ZIP does not compress data as tightly as some other algorithms, but other algorithms are too slow for general file system use.
