Sorry to drag up an old topic, but I'm always told that this is better ettiquette than starting a new one.
I've just installed the latest XNView on my shiny new desktop machine (running Windows XP Pro), and tried it out by browsing the \spectrum folder of one of my old hard drives (which of course I've installed in the new machine -- I don't want to lose 12 years' work). I was disappointed that XNView no longer seems to support .scr (and yes, I've read this thread and tried the suggestions here).
Am I overlooking anything? After all, although .scr was a bad choice of extension (almost as dumb as Wavefront choosing .obj for 3D objects), it isn't too difficult for a program to determine if a .scr is a Spectrum screen dump; if it's exactly 6912 bytes then it almost certainly is (and it's very unlikely that any Windows screen saver would be anywhere near that small). Likewise, if it's exactly 12288 bytes then it's very likely a Timex hi-colour screen dump, and if it's exactly 12288 bytes then it's almost certainly a Timex hi-res screen.
