I have a problem I cannot figure out. I have 155,000 photos in 1120 projects in A3 (ver 3.2.4). My photo files are all referenced on external hard drives, and the A3 library folder resides on my imac hard drive in the pictures folder (I do have just a handful of older projects that are not referenced).
I started to remove previews in the Aperture library to make space because my 500GB internal hard drive is almost full. When I got into the Aperture folder I found this:
My preview folder is 39GB for 488,000 items and my thumbnail folder is 173GB for just 4504 items. What is happening here?
I have a just few duplicates of slide shows at different resolutions that I use for presentations, so I don't understand 488,000 previews, and how can I have 173GB of thumbnails for only 4504 items?

Aperture Library a Mess

Aperture stores a thumbnail for every image in your library, but it may not have a preview for every image. Aperture also stores lots of sizes of previews for every version of an image vs a single thumbnail, even though the compression could be high on the previews and thus consume much less space. Are your thumbnails large? That could make them consume lots of space too. Also if you publish photo streams those get new previews stored in the previews folder, and possibly Facebook previews if you have Facebook turned on.
