I don't know anything about Mac's, but my guess is that there is a video aplication that also uses the .hdz extension (my Windows computer does that with .vue files (vue scenes and also a king of Video file). It also misidentifies Visual C++ .obj files as Wavefront.obj files. That only affects the icons used, however and doesn't have any affect on the files themselves, They will still work as they should.

If this is true, then why (if I look in another HAND Folder , say P5) I see the same file extension and associated PNG (and these display their thumbnails correctly...). I checked the "OPEN WITH" info and both the working and wierd examples and al are tagged to Poser6, so I don't see that another app is targeted. And, the PNG files they need are there and they are not corrupt. Perhaps a MAC guru can weigh in on this... Very strange. As it sits, the files (as you say) do work--- but since I can't see the thumbnail-- it's hard to know what the selection miught really be...

also... sorry that I seem to have a double posting going on this... I don't knowhow to delete the duplicate.

You can't eliminate the other post. This is something that takes people many months or years to learn, even though previewing and editing the message first would obviate that. But posts that you think you delete are stored somewhere anyway, to be used as evidence later (hey, just kidding!).

Apparently CL/e-frontier didn't bother to do a google search to learn that the hdz extension was already in use with some obscure gaming file, as well as a Windows help file. But there's no way Apple would be associating either file type with a video file, so I guess it's just another stupid Panther finder glitch. That's the weird thing about cargo-cult coding, as it applies to bugware like Poser or Panther or Tiger. Nobody will be able to explain it, there'll be no manual entry anywhere about it, and people will blindly wait and hope that the next release will be marginally better somehow.

The Finder acts up funny every once in a while for me too, showing the wrong icon for some files. Goes away after a reboot. About the hdz extension - is there any 3 character extension that's not taken already, at all? One of reasons why IMHO the .3 extension file typing should finally die and why I hate Apple for adopting that on OS X (just because everyone jumps off the bridge, you don't have to do it too).

There is no length limit to the file extensions on OSX. Poser or any other app can use .whatever if you check the new iWork word-processor it uses .pages the preference files are .pref The 3 letter code problem is Poser trying to stick to age old DOS conventions.
