[SOLVED]Output names of models and performance

tobix10

Hello, I want to iterate over a few files in directory and use 4 classifiers on each file.
How can I change output names(model and performance vector) to know which result refers to which file ?
Now I have something like this:
Performance Vector(PerformanceNaiveBayes)
Performance Vector(PerformanceNaiveBayes)
...

but I want:
file_name1(PerformanceNaiveBayes)
file_name2(PerformanceNaiveBayes)
...
