If you only want to concat the files, I would use some shell-tools,
like "cat" on Linux or "copy" on Windows, so

copy C:\Users\inshu.chauhan\Desktop\ForModel_600\*.arff
C:\Users\inshu.chauhan\Desktop\test2.arff

should do it.

Yes I just want to concat the files , not parse/mangle the files. =A0How ca= n
i simply read all files in a folder in my computer and write them into a single file ? just by 'printf ' is it possible ?

Reread Roland's message, quoted above for your convenience.

Not sure what you mean by printf. =A0Why would you use C to do it?

If you need to do it in Python, remember you can read a file with the read(= ) method, and write one with the write() method. =A0They pay no attention t= o newlines, delimiters or anything else. =A0Just create the output file, th= en in a loop open the input files and loop through each (read doesn't n= ecessarily get the whole thing in one pass)

You'll spend lots more energy on the mechanics of finding the files the= n on the copying. =A0But perhaps the shutil module will have some further s= hortcuts.
