Assuming the files' last line always ends with a newline and the files use 
the same newline convention:

OUTFILE = "/path/to/outfile.barf"
infiles = glob.glob("/some/folder/*.arff")

with open(OUTFILE, "wb") as outstream:
    for infile in infiles:
        with open(infile, "rb") as instream:
            shutil.copyfileobj(instream, outstream)
