Кратко: При завершении работы достает CD из привода, не потребляет ресурсы, работает с несколькими приводами.
ExtraCD - this program ejects your CD on system shutdown.
It can operate with several drives ejecting and
inserting one after another if there was disc in it.
You can define the sequence of ejecting,
the sound on eject, delay before inserting ejected drive
and some other settings.
If you will hold Shift or ScrollLock will be on while system shutdowns,
drives won't be ejected. You can disable last option through settings.
If drive ejects even if there was no disc, try to increase
'Spin-up time' (in most cases "4" should work fine).
Almost all settings (except 'Installed') stored in 'ExtraCD.ini'
file in windir.
