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

R32PCPU
R120PCPU
*1 The file size unit (cluster size) differs depending on the firmware version and production information of the CPU module. ( Page 747
Added and Enhanced Functions)
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 the R08PCPU, it is written as 2048 bytes of data because the file size unit of
the data memory is 2048 bytes.
