How to burn a 10 GB folder to DVD

There is an app called Big Mean Folder Machine that can split your 10GB parent folder into smaller folders each of which can be sized to fit on 4.6GB DVD media. I have used BMFM and it works really well.

That said, for archival purposes, it would be better to copy the folder/files to an external drive, preferably a traditional hard drive. In fact, for archiving, you really need to make at least 2 different copies on different media. The OWC Mercury Elite Pro mini 1TB drive is one to consider.

• Traditional hard drives, being magnetic media, remain well suited for archival storage; and data can be recovered more readily if something ever goes wrong with the drive.
• DVD media is very slow, it is limited to 4.6GB (or about 8.5GB if dual layer) and issubject to "disk rot" over time.
• Flash drives are not sufficiently reliable for long term storage; their memory cells gradually degrade. Flash drives are inexpensive because they are designed for short-term lifespan.

You might want to do what I do: get a bare SSD (SATA) and connect it to the Mac with a SATA to USB adaptor: Then copy the entire folder to the SSD:

Otherwise, just add the subfolders to another folder till it get's around 3.5 GB and burn that folder to a DVD. Then do the same for another new folder, etc., etc.

That's the most practical solution - copy the folder to a USB flash drive, especially since a 32 or 64 GB drive costs so little. DVD±R disks vary in quality, and as a result, the longevity of the brand that you use is uncertain. DVD±RW disks are more susceptible to degradation from long-term storage in a hot environment.

Would agree except for the unreliability of Flash Drives.
