Data lost without deleting anything

[alperduran217]

Hello.
I needed to merge two iphotos libraries. First i copied only the Master and the Preview files from A library to the other B library. When i execute the B library i couldn’t see library A’s files and i tried to copy all files from A to B but when i do that because of the empty Master and Preview files i lost all of my pictures. Now the iphotos shows me only the preview pictures. I didn't delete any file. How can i recover my photos?

You should never manually mess around in this iPhoto library packages.

I'm assuming here you don't have a backup of the previous two libraries?

The best option I can think of at this point if to manually move every master photo into a new folder. Then create a new iPhoto library from scratch and import all those photos into the new library. You will lose any edits of course and any organizational structure like events etc will be gone, but that would get all your photos back in one iPhoto library.
