In many cases a special setup for users is required. This setup can be created easily by putting shadows of programs to be run (for instance Communications Manager) into the Startup folder. This folder is opened when the operating system is initially loaded (known as "initial program load" - IPL - or "boot") and the applications in it are then started.
Though a shutdown remembers the running applications and restarts them after booting the system there is still a need for the Startup folder. Shutdown only remembers what was running at the time, whereas the Startup folder has a fixed set of applications to start no matter if they were running at shutdown or not.
Startup Folder Sequence
It is also possible to order items in the Startup folder. First, display the folder using an ordered view (that is, anything except icon view non-grid). Then drag items into the folder in the required order. This can be useful for programs which are dependent on others being started before they are started.
