[Zope] Zope and MS-Frontpage inter-operability

Hi, I am trying to use a site developed in MS front page. The problem is that Frontpage uses folders with underscores e.g. _themes , for storing images, css etc. Python (and therefore Zope) does not seem to allow folders (or any object in fact) to have a name that begins with an underscore. Has anybody successfully used Frontpage and publish it to a zope web server? Thanks for the help Roberto P.S: I apology in advance for mentioning frontpage in this forum
