Now that I have Catalina downloaded, you said I may have a question about a folder on my desktop. I do. It says Relocated Items. When trying to open them I get the message "No application set to open the document. Can I ditch it to trash?
Also, I curiously looked at my new HD with D/U. It shows 11.09 gigabytes in use, other volumes 27.71 and 82.19 GB free. What is using the 27.71 GB other than Catalina? My apps? Thanks.
