First of all *never* attempt to save directly to or Open a file from a CD,
DVD, floppy or any removable media. Always copy/save to a hard disk then use
Windows Explorer to copy/move the file.
If the file is Read Only then you cannot save changes to that file. What you
can do is Save As a different file, but again, not directly to removable
media.
Also, if you Opened the file from a CD/DVD, *that's* why it opens as Read
Only. Copy the file to your hard drive & open that copy. If it still opens
as Read Only, close the file, right+click the file icon in a file management
window, select Properties form the shortcut menu & remove the Read Only
check. You should then be able to edit the file & save changes to it.
