This is a simple ASCII file containing the full path to the last Cascade Connect Setup file which was saved. At installation time the contents of the cs_setup-ini-file points to install-path\cascade.ini which is usually c:\cascade\cascade.ini.
If cs_setup-ini-file is not passed then cs_setup utility opens with no default configuration file.
The cs_setup.exe executable starts the Cascade Connect Setup window, which allows for the maintenance of configuration files that are read by the cascade.exe executable. For more information about using the Cascade Connect Setup window see the Setup chapter.
