If you are on a Mac or Linux machine and don't want to install software just to burn a large file across multiple DVDs, here's the simplest solution to accomplish this.

 

You can use the following command to split your large file into chunks:

split -b4000m <large file name> <prefix>

This command will split your file into 4G files. Each file will be named <prefix>aa, <prefix>ab, <prefix>ac, etc.

Burn each file to a single DVD. (You can use -b8000m or 8G chunks if you have dual layer DVDs)

 

Load all the files on the destination machine and reconstruct the file from the chunk files.

If the destination machine is Linux or Mac use:

cat <prefix>aa <prefix>ab ... > <original filename>

So if the <prefix you chose was "chunk" and the original filename was "Ubuntu.vmdk", the command would be:

cat chunkaa chunkab chunkac ... > Ubuntu.vmdk

 

If the destination machine is Windows, from cmd prompt use:

type chunkaa chunkab chunkac ... > Ubuntu.vmdk

The "type" command behaves just like the "cat" command in Linux.
