(hmm, using file as a variable name is not a good idea, it hides the  
builtin type of the same name)

Let's say, if the file name were "abc.txt", you should open the output  
using this name: '../archives/abc.txt'
To build a path from its components, use os.path.join
So, replace open(file,... above, with  
open(os.path.join('../archives',file),...
