How long will it take to download my CS6 applications?

Is there a way to make the Adobe Application Manager download the archive containing the software on another disk? (I am not talking about setting a different install folder, my understanding is that the application downloads the files in a Temp folder on my C: Drive)
My problem is this: I got a SSD as boot drive but the size is very limited (Effectively 52GB) and I am experiencing troubles in downloading the whole suite: Illustrator, Flash and other programs do not have enough size to download and extract on my C: drive.

Looking forward to an answer.

You can try adjusting the location of your temporary directory.  This will be a system configuration issue though and not adjustable through the Adobe Download Assistant itself.

can I select pictures before full extraction takes place?

No the application must be fully downloaded and installed prior to being able to be utilized.
