    You can do all this very comfortably within a Mathematica notebook.
Without knowing the details of your problem, here is a schematic:

First go to the appropriate directory and get the names of the data files in
a list.  I assume they have file extension ".dat":

SetDirectory[ ...]


Define a function to all the work on one file and save the result in a file
with a different extension

processDataFile[fn_String]:=Module[{ result  },

Then treat all the files


This assumes that the result is some kind of Mathematica expression and you
would be happy to get that expresssion saved in a file.   I suspect you
might want a notebook for each input file, containing plots, tables, etc.
That is also possible - see functions like NotebookPut, SelectionEvaluate,
.... I'm sorry I don't have time to think through the details.
