1: There is no auto import that will create the file structure. You will have to do it all manually by first creating your album in LR CC called Birthdays for example. Then import all your images for that folder then move them to the folder you created. Repeat for all folders.
2: I'm not fully understanding this question. You can set up your folders however you want them in Windows? LR CC Cloud does not work the same way as OneDrive. Once you get your images in the LR Cloud you don't even need them on your local drive any more unless you want to have an extra back up.
Thanks for the reply ref
1. I thought that might be the response, shame that's not part of the import for people with lots of pictures moving tolightroom
2. I get that the pictures are in the cloud and only a % of disk space is allocated to local storage. There's a setting to store 100% on the local drive keeping original local copy. I set that path to my one drive copy ( I like a backup of a backup) when browsing to that location the folder is a GUI i.e 3beb6bdb8af24b1b8b89d80e35218bc4 then a folder called 'originals' then Year, only '2017' shown on my test setup. then broken down to date.
The reason this is a problem is my family might not use lightroom. If they want to view the family pictures they log onto the computer browse to my servers share to view. Where they are used to seeing the folder structure set out this wont be possible.
Maybe I'm asking too much.
