Accessing InstallShield "Support Files" from DTF (Managed Custom Action)

I have a bunch of .SQL scripts placed in the "Support Files" view of InstallShield.

I want to access those S开发者_如何学CQL scripts in my custom action (via DTF). How can I do that?

InstallShield has a custom action to extract support files, called ISSetupFilesExtract. I guess when you add a support file, this action is automatically scheduled by the InstallShield engine. Hence, you can schedule your DTF custom action after ISSetupFilesExtract and address the support files extracted to the temp directory.
