Joe, a user, copies a text document off of a CD drive into a folder. Joe has full control permissions on the folder. When Joe tries to edit and save the document, the system prompts him to save it…

CD/DVD media is read-only by nature, and Windows preserves the Read-Only attribute on files copied from optical discs to the hard drive. Even though Joe has Full Control on the folder, the file attribute itself restricts overwrite saves, forcing the application to prompt for a new save location. The fix is to uncheck the Read-Only attribute in the file's Properties dialog.

A damaged CD would cause copy errors or a corrupt/incomplete file transfer, not a consistent save-location prompt on an otherwise openable file.

A corrupted file would typically fail to open or display garbled content, not produce a prompt asking for a new save location.

An incorrect file extension would cause the wrong application to associate with the file but would not trigger a save-to-new-location prompt.
