The OP actually wrote 'Explorer' and from context he obviously meant Windows Explorer, not Internet Explorer or some other proprietary program. Wine's purpose is to allow proprietary Windows applications to be run as Linux applications, so extending it to support windows utilities such as Windows Explorer is outside its remit, even if it was possible, when the exact native equivalent, in this case Nautilus, is available. > If proprietary applications provide a shell extension thumbnailer for > their own binary file format (not bmp, don't be ridiculous) > Why not? Its still a reasonably common Windows file format that nothing much except GIMP supports natively under Linux. But you entirely missed my point, which was that, as Nautilus is what the OP will be using to find files and it is easily extensible to handle any additional file type, so it is reasonable to expect it to provide an extensible mechanism for dealing with thumbnails. However, at present only the thumbnail display size appears to be configurable. So, if the OP feels strongly about it, the way forward is to raise a bugzilla request against Nautilus for extensible thumbnail generation and display. Martin
