In order to help, we'll need to know what your path looks like. For instance, are the dates organized into directories like this:

example.com/2012/07/04/file.xls

...or like this:

example.com/20120704-file.xls

Give us a couple of examples of what your path looks like, and we can point you in the direction you need to be.
