Specify whether the release should be compressed:

- Compressed—Select this option to compress all of your product's files into either a single executable file (Setup.exe) or a single Windows Installer package (.msi file).
- Uncompressed—Select this option if your product's files should not be compressed, and if they should be in a subfolder of the folder that contains your installation package.

As an alternative, you can use a custom compression method, which enables you to compress only the files that are associated with one or more features into .cab files. To set custom compression options, you must use the Release Wizard.

Note that when you use the Release Wizard to configure custom compression, InstallShield changes the Compression setting in the Releases view to a read-only value of Custom (One Cab per Feature) or Custom (One Cab per Component). To change the compression from a custom method to the standard compressed method or the uncompressed method, you must use the Release Wizard again; you cannot do this from the Compression setting in the Releases view.

The output of the build process depends on your media type, compression, and spanning settings.
