I copied your System Events script and just now took a look at it. You added the two folders together in the top line.
repeat with theFolderAlias in {folder "Mac SSD:Users:robert:Desktop:Sync Folders Local Backups:Local Documents Archive:", folder "Mac SSD:Users:robert:Desktop:Sync Folders Local Backups:Local iCloud Folder Archive:"}
So, assume I can just continue adding all seven of my folder paths to that top line following your example. That sure makes it easy.
Also, I pointed my better half (sometimes referred to as my “live in accountant”) at the line “on some of my Macs.” I’m falling behind, I only have two.
