Changing a file from read only?

[Student]

I saved an existing file from my computer to a cd to be able to work from my
laptop, but when I try to save any changes to the cd it tells me it's read
only. I don't see any commands putting it on read only and it's not read
only in my C: drive. How can I save any changes made on the cd?

Check out the file properties in Explorer and remove the Read Only
checkmark.
When you copy data froma read-only medium like a CDROM, this is normal
behavior.

After you are done making changes to the copy on the harddrive burn it
to cd.
