My iCloud Drive in Preview is empty where are my files?
So you're saying that there is no &quot;iCloud Drive&quot; in the sidebar, or that no files are showing up in it?
-If it's the first one, then you can re-add it by going to Finder &gt; Preferences, clicking on &quot;Sidebar,&quot; then clicking the checkmark next to &quot;iCloud Drive.&quot;
-If it's the second, then you might have accidentally unchecked &quot;iCloud Drive&quot; in the &quot;iCloud&quot; icon on System Preferences. If you're on Catalina, you have to click &quot;Apple ID&quot; at the top of System Preferences instead, then &quot;iCloud&quot; on the left.
