Hi all os.walk() is a nice generator for performing actions on all files in a directory and subdirectories. However, how can one use os.walk() for walking through two hierarchies at once? I want to synchronise two directories (just backup for now), but cannot see how I can traverse a second one. I do this now with os.listdir() recursively, which works fine, but I am afraid that recursion can become inefficient for large hierarchies.
thanks for your help André
