LabelWizard is an AppleScript droplet that comes in handy after a Clean Install of a new Mac OS when you want to label (red, for example) all items in the new System Folder before any other (non-Apple) item is added.
This makes it easy for you when you do a new Clean Install in the future. Why?
Well, when moving items from the old system folder to the new one, you can easily recognize all (old) color-coded Apple-related system files which you should NOT drag to the new system folder.
LabelWizard requires Mac OS 8.6 or later.
For your convenience, I have added a script named Change Label of All Items that contains the same basic script as in LabelWizard, and that you can put in the Scripts Folder in your System Folder, under Finder Scripts:Folder Tools, supposing that you have installed the OSA menu.
Both 'LabelWizard' and 'Change Label of All Items' are freeware, but copyright-protected:
