I had started a new library for 2013 and had just over 10,000 images in it.  The library was a managed library.  I had deleted several hundred images and then moved the masters to an external drive. 

After the files were moved I checked the library in finder and it shows a size of 16 GB.  I have a smart album looking for managed files and it is showing none, so I am confident that all of the masters are moved. 

 

Is 16 GB a normal size for a referenced library?  Are the previews using this much space on the drive? I have the preference for previews at 2560 x 2560.

 

Thanks in advance for any insight.

    Omni DiskSweeper (free) will show you the storage requirements for each of the Finder folders in your Aperture Library file package.  I think that will allow you to answer your question based on your data.

     

    It's a sweet little utility.  And in use should be straightforward.  If it's not, post back.

    PS:  Do not use Omni DiskSweeper to delete any files inside your Aperture Library!

    A quick calculation:

     

    Your previews will have roughly 5 megapixes with these settings (2560 x 2560 x 3/4), and depending on the complexity of your images (the amount of detail) the size of the jpegs should vary between 1 and 2 MB.

    So with 20000 images in your library, your high quality previews will need ~15 GB, also your library may contain an iPod Photo Cache, if you are syncing with iTunes, plus thumbnails.
