I don't like Cloud! Please help

Which version of Lightroom were you using?

If you use Lightroom Classic and synced all your images to the Adobe Cloud, be aware that LrC only uploads Smart Previews of your original files. These SPs would therefore be pretty useless if you lost the local HD that contained your originals (and didn't have a proper backup of them). To delete all the smart previews from the cloud, login to your LrWeb account via your browser (lightroom.adobe.com, use the same Adobe ID credentials as you use for LrC), click on your avatar top right of the browser window, select Account Info from the drop-down menu, then you'll see the option to delete the Lightroom Library (all your assets stored in the cloud). But only do that if you are certain that you want to delete everything from the cloud.

If you were using the Lightroom desktop app, everything you synced to the cloud would be full original files and they should still be there.

If you are subscribed to any of the Lightroom-Mobile Apps, then, by nature, they store your image files in Adobe Cloud storage.

If you need to download all files from the Apps Cloud storage then you may be able to use this-

DOWNLOAD CLOUD PHOTOS

Only after confirming that all files have downloaded should you consider deleting files from the Adobe Cloud.
