I need to build an MSI that does two things:
1) Copy a folder from a DVD to the install location.
2) Call another MSI via command line and pass it some parameters, including the install location.

The folder I am copying in part 1) contains over 25,000 files. I don't want Installshield to *know* about all these files, because it causes both installing and uninstalling to take forever. I just want it to copy the contents of whatever is in a particular folder on the DVD to the install location. Can I do this? I can figure out later how to delete the folder upon an uninstall.

For part 2) can this be done via a custom action?
