can't be replaced because it's invisible
I have my iMac and MacBook Pro both visible in Finder on my network. I want's to copy Adobe settings from one Library folder to the other. When I try to copy and paste, I get the error popup "The item 'XYZ.xxx"' can't be replaced because it's invisible." XYZ.xxx is the name of the file. I have admin read and write privileges in both folders. I can copy the files to the Desktop, but I get the same error then copying from the Desktop to the Library subfolder. I have tried the Terminal command "chflags nohidden", but nothing changed.
I am using Catalina 10.15.6 on both machines. These are not and should bot be hidden files.
