Wow great, thanks a lot era!
Hope you don't mind a follow-up question, what if i want to store in a file all those existing statistics files? And just just put spaces on those missing files?
Example
==>
statistics.1;statistics.2;statistics.3;statistics.4;<space>;statistics.6;......statistics.19; <space>;statistics.21;......statistics.34;<space>;....statistics.50

Hmmm..
