I need to see all of my past history pdf files in adobie cloud.

Hi michaelr,

As per the issue description mentioned above, you want to see the pdf file history in document cloud, is that correct?

You can check the files store on the cloud using the steps given in the following help document:

Manage and work with your files stored in Adobe Document Cloud

Thanks,

Shivam

Did you save the files in the Document Cloud?
