As far as I know, there is no way to get finder information for a 
single file within Rev. You can use the detailed files to get this 
for the whole folder but it is really not optimal if one needs such 
an info for just a single file in a folder full of hundreds of images.

Also, if you are concerned about retaining file/creator codes, you 
could/should retain also other finder info like file labels. 
Unfortunately, there is no way to get/set them from within Revolution 
as far as I know.

Theoretically, you should be able to use Rinaldi's externals GetFInfo 
and SetFInfo. I say theoretically because GetFInfo causes a hard 
crash and both Frederic and RunRev folks blame the other (see bug 
855). Furthermore, there are no OSX versions of those externals.

IMHO it would be reasonable to support platform-specific features 
like these through an external.
