How to add files to a disc (multisession)
Burned a disc but have room left? cdBurner can add another session of files to a multisession-capable disc instead of wasting it.
Step by step
Connect the burn agent
Open onlinecdburner.com. The first time, install the tiny one-time helper so the page can reach your drive — after that it just works.
Insert a blank disc and pick your drive
Put a blank disc in your writer and select it. cdBurner shows the disc type and free space.
Add the extra files to append
Click Files or Folder and choose the extra files to append. A live gauge shows whether it fits.
Set options and burn
Pick a write speed, keep Finalize on for maximum compatibility, then click Burn disc.

Why cdBurner is different
There is no other tool on the internet that burns real, physical discs straight from a web page. cdBurner is the first of its kind.
- 100% free — no trial, no watermark, no nag screens.
- Private — files are written locally and never uploaded to a server.
- No bloatware — one small signed helper, not a heavy install.
- Built on Windows' native IMAPI2 engine, so your discs read everywhere.
