File Size Unit in Memory

The minimum unit of capacity for storing a file in the memory is referred to as the file size unit (cluster size).

Data is written in the unit of the file size (cluster size). For example, when 464 bytes of CPU parameter is
written to the data memory on R04CPU, it is written as 1024 bytes of data because the file size unit of the data
memory is 1024 bytes.
