One file can handle a maximum of 1650 blocks (recipes). Data
transfer is carried out in blocks. Also, the maximum number of data
items in 1 file is 10000 or 5000 when the data is 32 bit.
The number of files, blocks, and data that can
be set changes depending on the ratio of each one.
You can also register files in multiple
folders. Up to 8999 folders can be registered, but only one folder
can be stored in backup memory (SRAM).
