adressbook files...

Hi

Do somebody know how software system work in a
regular cell e.g. Nokia 6230, not smartphone.

Concerning the Adressbook:

1. Is all contacts stored as one single file
or
is each contact stored as a file itself, which
means the adressbook folder consist of multiple
files (of contacts)?

2. what´s their file extension? I got confusing results
in google as .CSV , .vcf (visit card file)
and .pbf (phonebook file)

3. Where can find such information or articles about
the structure of the "software system" in phones?
I´ve heared it´s similar to computer´s OS, but 1000
times simplier and containing a similar files n folder
system

4. Lastly check this link, who says you need drugs to
get hallucinated
