Glad you are all sorted, I know that it sucks when you ask a question but never get a reply, I did that when I first started using AM, but I ended up finding the solution that I wanted by trial and error.
Sadly sometimes though, it is better to unzip stuff as I had my PS2 zipped and I tried loading up one rom direct from the emulator and it caused it to freeze, so in the end I unzipped all of my files. I am looking at 4.15 TB just on that alone, plus I am around 1,000 short on the full collection. I am now looking at 18 tb hard drives as I have three SATA ports free now with a new motherboard.
As I am very anal and OCD about things, I want the whole lot which is pretty expensive I am already on £660 worth of hard drives, and 18TB will set me back another £300 per drive, so in the end I might replace all of the 8TB's otherwise I will have to build another PC just for PC games.
