I guess the easy way of doing it is to paste the two files in one, and

The problem with this method is that my files are quite large and I have a few thousand of them(I have a C program which does this analysis for me, but I need to double check the results for some of them),  so to add another column to my output would nearly double my program's running time(which is already at more than an hour, and already dominated by read-write time)
