Can others upload material to Creative Cloud Libraries and Folders

[#1]

I've seen information that says you can Collaborate with others and if you allow them edit the files they can edit, watch, delete etc files.  Can they also UPLOAD files to your folders?

I would like to allow my family to upload media from their phones to my folder without giving them access to my account.
