In that case, I think you just need to devise your output file name
scheme, and it looks like you want to use 'os.path.splitext(base)[0] +
".csv")'. Then  output each file in the same for loop, before you go
back for another input file. Just read in the file, do whatever you want
to it, and then write it to the new file name, all in the same loop.

I don't see any need to loop through rootobs a second time.
