How do I locate the books accessed through Acrobat Digital

I have been using Acrobat Digital Editions on a Windows 10 desktop computer. I am in the process of setting up a Windows 11 desktop computer. I have downloaded the Acrobat program to it.

My data is stored on external hard disc drives, so it was simply a matter of making the physical connections.

I want the Acrobat program on my new computer to access these books. Where are they located?
