Aperture 3 and thumbnails to clean library?
I wanted to clean my aperture library (70+ Gb) to move it to my new SSD.
This is what I did.
1. Rebuild library database and repair.
2. Deleted all the previews from library.
3. Backed up 50,000 pictures on an external drive and then deleted the masters (referenced).
So far I did not get much, the size went from 70 to 64 Gb.
4. Made a copy of the library, right click to show content and deleted the thumbnails folder (40 Gb).
5. Launched Aperture on this library to let it rebuild all the thumbnails (took almost the whole day).
This worked! My library is now 15 Gb. The thumbnails folder within the library is only 10 Gb.
My question, is it possible that Aperture keeps all the thumbnails in the library when deleting the masters??
