Thumbnail Viewer windows 8


does Thumbnail Viewer on windows 8 work?? mine doesn’t work properly. some of files does work but many others doesn’t.
is there a programm to install for Thumbnail Viewer??

The shell extensions needed are installed with Rhino.
My guess is the files that don’t preview don’t have one in the file.
I think maybe SaveSmall will strip it out.
Try opening one of these files make a minor change and save it.
Then does it preview?
