The PICO has no filesystem. IN use you hold a button down while powering 
up and it's Flash presents itself as a USB drive. You copy a special 
binary file of compiled code onto that 'drive', and it reboots and runs it..

Free flash ram is available for program use as well, but its fairly 
tricky to use it - its read a sector. erase a block write a block level 
primitives

In practice, you don't normally do that - most code is simple and uses DRAM.
