CD or DVD file too large to burn

A CD can hold ~700MB of data.

A DVD can hold ~4.7GB of data.

How large is the file you are trying to burn?

What software are you using to burn your disc?

• Again - What is the size of the file you are attempting to write to disc?

Select the file and press Cmd-I (⌘I) to see.

• Is the file located on your computer or in the cloud?

If in the cloud, place a copy into a local folder and try to burn it from there.

• What brand and type of disc – CD-R, CD-RW, DVD-R, DVD-RW – are you attempting to write to? Some brands are better tolerated than others in inexpensive dvd burners.

• Has some data already been written to the disc before?

If so, it may not be possible to add additional data to that disc. Try burning to a new disc.

I seem to recall that a CD-R could be amended until full or finalized (?)... but it's been a long time since I've used them. I could be wrong - and probably am. I've had a lot of birthdays. 😉

If a CD-RW, then it could be erased and rewritten. Likewise with DVD-RW.

You may be right: ‘sessions’ now comes to mind. I think they may not have been available when I first started using CD-Rs, and maybe I was only twice successful with sessions.

Probably became reliable a long time ago.

A CD-R can only be written to once, as I remember.
