Hi you can shift click or command click everything in the library, then right click and "Move Selected Items To" > whichever library you want to move them to.
Thanks for reaching out. In addition to response given earlier, I'd request checking out this help article(https://helpx.adobe.com/in/creative-cloud/help/libraries.html) to know how to manage assets in Creative Cloud library.
Hope it helps.
Thanks, lambiloon. That got everything together. I don't understand why it creates a new library with the same name every time I want to store something in my library.
Ashutosh_Mishrs - the link leads to a page no longer there. I get the message that the page does not exist.
My apologies. Link has been updated. Thanks!
The link still doesn't work for me!
Thank you, lambillon. That link worked and was exceedingly helpful.
