The free Volo View Express does view both DWG
and DWF files; however, it does not view the new AutoCAD 2004 DWG
files. Volo View Express is being discontinued, so it is not going to
be updated to add AutoCAD 2004 DWG support. Similarly, Volo View Express only
views older DWF files. The DWF format has recently been updated so that DWF
files can be plotted to scale if they are generated with that
intent.
The Autodesk Express Viewer is the free viewer
from Autodesk. You are correct in that it is DWF-only, but it is free and does
view the latest DWF format. It does not have the markup and measurement
capabilities of Volo View. It is Autodesk's recommended solution for plotting
DWF files to scale, although some issues have been noted in the
newsgroups.
Now if you really need DWG viewing in addition to
DWF viewing, Volo View 3 will view AutoCAD 2004 DWG files. The Volo View 3
package is being offered for $49. It does work well on DWG viewing. There are
"object enablers" that are free of charge and can be downloaded and added to
Volo View. These enablers enable Volo View to view more intelligent CAD formats
such as Inventor files; however, people have had mixed results with these
enablers. Given this and that the Autodesk Express Viewer is easier to download
and install, I would go with the Autodesk Express Viewer and define my own
process to keep original DWG and generated DWF files in sync.

it a Volo View Express for 2004? Express Viewer opens only DWF!
THANKS!!
