I have PLENTY of RAM yet Photoshop is saying there isn't enough to save my design. WTF?

Have I gone completely stupid? There's only one layer, the file is relatively small, and I have over 90% available RAM on my laptop. I have hundreds of designs on my desktop and this laptop is the exact same type just up to date and with more of everything. It actually out performs my 3 year old desktop.

So...what's going on?

RAM is the memory your computer uses to run programs. It's not the memory your computer uses to save data. That would be on your hard drive.

If there is no room to save stuff, it means your hard drive is full.
