Aperture 2 All Projects will not allow viewing individual files

Question

In the Library/All Projects selection are 4 projects, 3 allow me to click on any image and view it full screen. The 4th will not. Clicking on a picture won't open it, nor can I copy any files from it. How can I fix this? All of my pictures are stored here, over 10,000. And once there was a smart folder called ALL PICTURES in the LIBRARY but it has vanished, How can I put it back?

Answer 1

I tend to limit the size of each project to around 1,000 images as I notice a performance decrease thereafter. With 10,000 in one project you may have a decent slowdown.
Can you create a new project and drag pictures from project 4 into it?
If so divide up your huge project into smaller chunks.
Have you tried to rebuild the library/consistency check (hold alt as you start up aperture and run the checks in order)?
To replace the smart album, click on library, new - smart album - then choose, for example, rating is greater than 'unrated'. Then call it unrated or better photos. Again I tend to steer away from this mega folders due to the resultant slowdown.
Hope this helps
