Q: opened my aperture library in photos

looks like everything is there and looks good......but now i have one aperture library and 2 photos libraries? the aperture library was about 2 TB and now it looks like photos placed 2 photos libraries (that show 2TB each but they aren't, i can tell by how much space is used and left on the HD) and my aperture library is still there as well.....no matter which photos library i open, they both open to the same library, which is my "old" aperture one...

i guess all 3 are now necessary just to have this library for photos? i am not really planning to use it in aperture again...

MacBook Pro, OS X El Capitan (10.11.1)

    Even if the new Photos Library and the old Aperture library are showing the same size in the Finder, they are not using twice the storage. All original images and previews in both libraries are hard linked. They are separate files of the same size, but are sharing the same entry in the file table and using the same blocks on the disk.

    See these links:  Photos saves disk space by sharing images with your iPhoto or Aperture libraries - Apple Support

    and also:   Six Colors: The (hard) link between Photos and iPhoto

     

    You need only to keep the new Photos Library, but because of the hard links deleting the original Aperture library will not free any storage, until you delete the corresponding photos in Photos as well.

     

     

    If you opened the same Aperture Library twice in Photos the hard links will be sharing the same image files as the first Photos Library, so no new storage will be used for the second Photos library.

     

    You can delete any of the three libraries, depending on if you want to continue to use Aperture or Photos. The storage will only be released, if you delete theist linked file. The system uses a reference counter.
