File Media Library
InstallShield 2020 » InstallScript Language Reference
The file media library contains your product’s files and all the information that you entered in the InstallShield interface about your installation’s component, feature, and setup type settings.
The file media library is created when you create a release for your project. It is defined by Data1.hdr, the InstallScript header file. It also has a media name, the default value of which is contained in the MEDIA system variable.
You can set and access information in your file media library using the InstallScript feature functions.
Note:Some InstallScript feature functions are specifically reserved for use with script-created features.
