I have only been using Aperture for about a week and my little macmini ran out of space last night with all the RAW files I have been importing. So i thought here is a good time to create a vault on my external hd, transfer the aperture library to that and then delete the library inside the mac. I thought that I could then be able to access all the files from the external hd in Aperture when I turned it on so I can get to the old photos again. Well, I expect i am doing something wrong but I can't get to the files now through Aperture. So I thought lets start again and transfer the Vault back into the library. But the vault just copied back into the Pictures folder in Finder and I can't seem to do very much with those files. I'm not worried yet. I can still see the original files are there with the full sizes, but I can't get them back into Aperture. I should know by now that doing this kind of organization last thing at night over a bottle of wine isn't a very good idea. Things this morning don't seem to be much clearer though! Could anybody please point me in the right direction?
