SPIFFS flash memory addresses

[PramoSan]

Hi all,

I referring the spiffsexternal example to save multiple text files in the TI Launchpad LAUNCHXL-CC1352R1.
How should make boundaries within the files in spiffs file system. in the nvs driver I can achieve this with region offset address.

SPIFFS_write(&fs, fd, (void *) &message, MESSAGE_LENGTH)

But, this doesnt have a region offset value as NVS driver.

So, should I have to define multiple file systems and mount them to save my different files?
If its possible, are the region offsets handle automatically?
