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.

This ZIP includes both the viewer DLL and source code (Delphi).
I used the pascal header file from this post, with some corrections.
This plugin supports both file viewing and thumbnails.
