So far I've been able to create a file in the desired directory but it isn't pulling any of the data in the originating directory. Could please look at my code and tell me what I'm doing wrong.

I don't think what you pasted will work at all.  The r+ should produce a syntax 
error on the g=open(os.path.join(r+,files) line.

No real reason to get shutil involved in this.

try something like this (not tested):

outfp=open("c:\\output\\testing1.txt", 'w')
for root,dirs,files in os.walk("c:\\test"):
     for fname in files:
         if fname.endswith(".txt"):
             infp=open(os.path.join(root, fname), 'r')
             of.write(infp.read())
             infp.close()

outfp.close()

or if the files are binary:

use 'wb' and 'rb' instead of 'w' and 'r'

BTW - This will concatenate ALL the .TXT files in c:\test as well as any files 
in any subfolders into a single output file.
