Did you delete (a) your local documents from your iPad or (b) your cloud documents from Adobe Document Cloud?
Would you switch the file location to "Document Cloud" in Acrobat Reader for iOS?
Your documents should appear either in "Local" or "Document Cloud", if they still exist.
You can also use the web browser interface to check your cloud documents.
Unfortunately, there is no automatic backup for deleted local or cloud documents. It is not possible to retrieve documents, once you deleted them. Sorry for the inconvenience.
Doesn't exist anymore when closing file down it said it was saved to document cloud and I was able to go into it. So I believe the answer is I deleted it from the cloud as nothing is there
