Data in all files is one long continuous string - that's all a file is.
So do you mean you want to split the file into many files - or do you mean you want the file in a different format, suitable for a different purpose.
If the former - there are file splitting utilities.
If the latter (which is what I think you mean) - then it's unlikely, but possible. I would assume that the existing file and what you would like to turn it into, are both database formats. In which case you need to specify both the existing, and the desired format, before anyone could look to find a conversion utility. By format, I mean for which database - ie is it now in (eg) dBaseIII and needs converting to (eg) Access.
