I found the solution by reloading the app & located the files using EasyFind.app to ensure where they reside. Then, I was able to Empty Trash cleanly. I would close this Post!
Installed Vers. 2.1.1 & uninstalled Vers. 1.2. Have in Trash, file com.alfredapp.Alfred.plist & folder com.runningwithcrayons.Alfred-2. Couldn't delete from Trash! How do I restore this file & folder back to their original location?
Appreciate your support!
