Sorry if I overlooked that. In and out of Xcode right now.
Yeah, I always remembered them as pointers to files.
It seems like terrible overkill to embed the fat data in the aliases.
The point that I was trying to make which obviously was not obvious is that if a screenshot saved out of the iOS Simulator is 44KB and the alias is 340 KB, then something is wrong.
The PNG file does not contain a load of data for its icon and the like, so it seems terrible that the alias must. It would seem that the alias should be able to resolve the location of the icon and use the original, or use a default file type icon representation if that lookup fails.
In any case, back to work.

Try making a Finder alias of a generic document, a folder, or something else that has a 1024x1024 icon. The alias will be over a meg in size. Yes, that’s bigger than back in 1992. Unsurprisingly, a 1024x1024 32-bit color icon takes up more space than a 32x32 256-color icon. Progress marches on.
