What exactly does it mean when my Pokemon black 2 loads up and says it deleted some files?

Question

it starts to say PWT data has been erased, hall of fame records, even the musical photos

Comments

Probably because the PWT data, hall of fame records, and the musical photos were erased, I'm pretty sure.
