The bottleneck in MOLCAS for disk size on a 32-bit machine is that the disk address is stored in a 32-bit integer. The address is word addressable, i.e. the unit is in 8 bytes. The sign is stored in the 32th bit, hence the largest possible disk address on a 32-bit machine is 2^31, i.e. the limit is 16 GBytes.
