RVF (RichView Format) is a rich text format used by applications created with TRichView components ( trichview.com ).
RVF file editor can be downloaded from trichview.com/resources/acti ... ontest.zip
RVF files usually have RVF extension (*.rvf), but some applications may produce RVF files with different extensions. This viewer recognizes RVF files by extension.
Known problem: this viewer is not shown in a preview pane.
I do not know why it happens. If DOpus developers can help, it would be nice. An example of RVF file can be downloaded with the editor (the link is in the first post) - readme.rvf.
