Moving photos to folders

When you export a photo out of the Photos library to a folder on your hard drive you're creating a new file. Note: If you drag the photo from the library to the folder you many not be getting the full sized version of the photo but only the smaller preview size. Always export out of the library, not drags.

If you don't want those same Photos to remain in the library you'll have to delete them from the library.

Every photograph is in the Library. Just like iTunes & Music app: every song is in the Library.

No copy is made when you add a photo to an album. Nothing is moved. An album is simply a list of images you want displayed together. The same image can be in 100 albums and use no extra disk space at all. Again just like iTunes/ Music, a playlist simply hold references to the track in the Library.

So, the key takeaway is that in these apps the Library is the central core, and everything else is a derivative of

that.

If that is not what you want then use an application that works the way you prefer.

Go onto the photos app then click your desired album, in the album scroll down to the bottom of the pictures and there will be a + icon in the place of another photo to add a picture.
