FastRawViewer is a viewer only (with many advanced features for raw culling than no other viewer has). It does not write files (excepting .XMP sidecars with labels/ratings/adjustments).
You may cull/sort/delete unneeded files with FRV, than convert keepers to DNG using free Adobe DNG Convertor utility, so any DNG-capable (but not X-Trans compressed capable) software will read these converted files.
