Windows Installer Editor Reference
If you select this option, you also might want to use short file names for
uncompressed files outside the installation.
See the description of Use short file names for files uncompressed outside
of the install in
6. In Cab Options, determine the makeup of your .CAB files. To minimize file size, use
fewer .CAB files; to minimize installation time, use more .CAB files. This is
unavailable if you select Uncompressed external files from Compression
Option above, or if you are working in an .MSI.
Quickest (new files and modules get cab file)
This option only works when you have an .MSI file open. This option is selected
by default when you select the option to compress files into external CAB files.
Any new files that you add to the installation, including merge modules, get
their own .CAB files.
One Cab (including modules)
Create one large .CAB file for all files and merge modules in the installation.
This option saves some file space by eliminating overlap in .CAB files, but
installation is slower than installing from multiple .CAB files.
One Cab per feature
Every feature in the installation gets its own .CAB file. This option is most
efficient on a CD or similar media, where file size is not an issue.
One Cab per component
Every component in the installation gets its own .CAB file.
This option is best for WebDeploy installations, where only required components
are downloaded.
The remaining options on the Media page are enabled in a .WSI only.
7. In the Custom Media Settings area, specify settings that are related to the size of
your media.
Share media destination/size info with previous media entry
Gives a media item the same size and destination settings as its predecessor's,
therefore, mark this for the second and subsequent media items only. Example:
This makes it easier to create a CD where some files are compressed and others
are not. You can create one or more media items with different compression
options but have them all placed on the same CD.
You can also use this option to have one distribution medium (example: a CD)
filled up before starting to place media items on a second or third distribution
medium.
See Example: Spanning an Installation Across Media and Sharing Media Size
Information on page 242.
Max Media Size
Enter the size of the distribution media as a whole number and select the
appropriate unit (KB or MB) from the drop-down list. To indicate unlimited size,
enter 0.
Cluster Size
Select the bytes per sector of the distribution media.
