I have never played with those LINUX cad proggies, but I can tell you that if you want to share your LINUX files with Windows, you are going to have to configure a samba server. For more information you can either search for Samba with Google, or you can try
samba.org.
Just make sure you dont manipulate the same file, at the same time, in both Windows and LINUX or you will corrupt your file. . .
