Can I retrieve my Cloud Files?

Also, you should always have a local copy of all files... if you don't have enough space on your computer hard drive buy a docking station and 'bare' drives for copies of your files

I use a Sata docking station and SEVERAL 'bare' drives for backup

Do NOTE the difference between a monthly subscription and an annual subscription with monthly payments

SOME programs are available Monthly https://community.adobe.com/t5/Get-Started/Being-charged-for-a-full-year-when-i-m-on-month-to-month/td-p/10248222 - links and pictures
-the special Photography Plan is ONLY available on an annual plan, with monthly or 1 annual payment

your files will usually be saved for a few months.  renew a subscription (one app for one month should suffice) and download your files to a location you control.
