How to import old site from hdd into MODx???

Hi!
I’m new to modx and I have question regarding modx import files.
Does anyone know how can I import my old web site into MODx manager?
This site is located on my hard disk.
Do I just have to copy folder in which my site is located somewhere to wamp\www\... ?
Or is it maybe possible to import these files through MODx manager?

I’ve copied all files into /core/import/ folder and than tried to import them through modx manager ’Import HTML’ option,
but nothing happened... I’ve waited and waited but saving process never finished.
When I typed :’http://localhost/modx/core/import/homedir/public_html/’ into my browser it showed this message:
« MODx Parse Error »
MODx encountered the following error while attempting to parse the requested resource:
« PHP Parse Error »
