Disk spanning allows you to specify how your setup will be spread across different disks. This property can be changed only in the Release Wizard.

The available settings are:

- Automatic Automatically split your release files over as many disks as necessary.
- Custom - Enforce disk size Display a warning and abort the build if any feature's files are larger than the disk size.
- Custom - Do not enforce disk size Build the release to span as many disks as necessary.

This property applies only to compressed release builds.
