I just copied all the files and data over to a Optiplex 7070. I have a folder for dropbox with files that I sync with dropbox on the web. Since the move I cannot access the local pc files unless I am logged into Dropbox.com. The files I cannot access have a file box icon over top the original icon for the particular file. What do I do to correct this? I am running the latest version of Windows 11. I also see this on my old pc, an Optiplex 9010 running the latest Windows 10.
