Or not... Using directories may be a way to do rapid prototyping, and
check quickly how things are going internally, without needing to resort
to complex database interfaces.
Just a quote from the history of usenet:
I wrote the very first version of
netnews as a 150-line shellscript. It
had multiple newsgroups and
cross-posting; newsgroups were
directories and cross-posting was
implemented as multiple links to the
article. It was far too slow to use
for production, but the flexibility
permitted endless experimentation with
the protocol design.

for the question of the OP:
import string
import os
namefile="..."
for line in open("foobar").readlines()
dirname,number=string.split(line)
os.system("mkdir "+dirname)
f=open(dirname+"/"+namefile,"w")
f.write("TEXT..."+number)
f.close()
Portability can be improved by using os.path or something like that.
