Macworld reader Jeff noted that when he uses the Locked option, files stored in iCloud Drive don’t sync this Locked property to the other devices. The Get Info window’s Locked option prevents changes on a single Mac, and modifies the item’s Finder icon. Locking a file doesn’t prevent throwing it into the Trash, but you’re prompted to proceed when you do so, since you obviously locked it with a purpose. A padlock icon appears on the file’s icon or preview. One way to prevent this: Select the file in the Finder, choose File > Get Info, and check the Locked box. It’s an easy matter to overwrite a file in macOS that you want to keep unchanged.
