here's another guess-

did you create a subdomain?

if yes- the way to access those files with a url is
http:subdomain.example.com

some hosts put the storage folder for subdomains WITHIN the main site's
public file storage. so you can also see the files at
http://example.com/subdomain/

but this can give you headaches until and unless you decide to treat it as a
distinct unique Site in dreamweaver.

Make a new site definition for the subdomain in dreamweaver, and use the
"host directory" line of the remote server info so the files go to the
correct folder on the remote.

Then- Do not edit any of the subdomain files when in the main www site
definition. Ignore that you can see the subdomain folder. Only edit
subdomain files when in the subdomain site definition.

Do not use dreamweaver's browse to file or point to file to make any links
BETWEEN the main site and subdomain. That would make a relative path which
will not work on the published pages. Only use full absolute http:// paths
when linking between them.

As to what you first asked- I'm guessing you want to move a working copy of
some files into the subdomain's folder as a starting point for it's pages?
Go into the hard drive and copy/paste the files. Move all needed things
included images/css/js and put them in the same relationship so relative
paths would work.

Short version- copy the contents of the site folder, open the subdomain
folder, and paste.
