Add static folder/files in my wordpress blog

Hi,

I have a site which has .html files. I have folders/files like
/2006/05/07/testpost1/index.htm
/2006/06/01/testpost2/index.htm

in root folder. I also have folders like
/tagarchieve/testkeyword1/index.htm
/tagarchieve/testkeyword2/index.htm
/tag/testkeyword1/index.htm
/tag/testkeyword2/index.htm

(All the above mentioned files are static .htm files)

Now I started using wordpress and have permalinks like /2006/05/07/testpost1/. Now my problem is accessing mydomain.com/2006/05/07/testpost1/ works great. however, mydomain.com/tagarchieve/testkeyword1/ or mydomain.com/tag/testkeyword1/ doesn’t works

Can someone help me on this.

thanks
