From crossrulz: "In the installer build spec dialog, look in the Advanced tab. Enable Media Spanning is right at the top."
I faced issues while creating an installer with a size of 2GB+. Unfortunately I had to upload the installer to a shared site that didn't accept files > 400MB. The want for a separate installer and process thereof delayed my delivery.
I remember from other software(s) having distro creation capabilities in size of lets say a standard CD size of 650MB, etc.
Wouldn't it help many if the app builder allowed splitting the installer in a defined packet size?
