Internal Memory Deleting

How do u delete the internal memory? i did it a few time but everytime i whether get them back when i turn the mpc on again or, like today, i got a whole new batch of samples & sequences in it out of no where(once i turned it back on). i want to delete it all because i don't know how else to save my projects to the flash card, as entire memory, without having to save these extra samples. i follow Mano's video tutorial on saving projects by the way.

Purge them -- read ya akai manual

yea ok, thanks. i read most of it, but i guesse my logic didn't lead me from deleting samples etc. to the purging. ive read it but didn't remember it. thanks

Sparq posted instructions a while back on this. I'm not sure if he started a thread or just replied to it, but if you search this forum, you'll find it.
