Creative Cloud Files - Please Help

Can someone help me with syncing or uploading files to Create Cloud?

I understand the Creative Cloud File sync has gone away (why would Adobe do such a thing).  I recently upgraded to 1TB for the purpose of having access to many files despite what device I am using. Now, I cannot seem to upload those files to the cloud. Is there even a way to do this? I have 1TB of space without a wayto upload files so they can be available to me when I need them? If this is  the case, are there any alternatives?

I was one of those who thought about canceling my subscription earlier in the year. I didn't because Adobe is so ingrained in my workflow, but i really need to start looking for alternatives, unfortunately.

Thanks for your help!
