Cannot be altered. Files copied onto a CD become read only. You can mark your own files as read only to protect them from accidental or thoughtless changes. If you want to make changes to a read only file, open it, click "Save as" on the file menu, use a different name and work on the copy. You can also, if you're sure, right click on a file, choose "Properties", and uncheck the read only box. To do this to a whole bunch of files, select them all, right click on any one of them, once again choose "Properties". You can then uncheck the box for all of them at one time. You can't change the read only attribute of a file on a CD. Windows fusses when you've copied files back from a CD and are rearranging them. Don't be fazed. ALPHABET
