Alcatraz is 17gb?

I am clearing up some old software... Went onto the remove programs section on Control Panel and I see the following:
Aerosoft's - Alcatraz : 17.1GB
Acceleration is on the list, at just 970mb or so. My entire FSX folder is apparently 17.0GB
Urm. Can anyone explain that? If I remove that, am I removing something much more than just Alcatraz or what?
Cheers
