Which file types does the CloudNine Native File Viewer support?

The native files that can be opened depends on the MIME type association on your local PC and whether you have the software installed. The CloudNine Native File Viewer currently only handles TIFF, JPG, GIF, TXT,PDF, HTM and HTML.

All other file types depend on local PC software. As an example, if someone is running MS Office they can open MS Office files.
