This is just a simple problem for most people but I have a G4 running OS 9.2.1 with old software including Quark 4 and Photoshop 5. Recently I upgraded my system software to Tiger and I have continued using Classic to access my old software. I presume because of everything I have running that I keep getting a window message telling me to delete some files because my start up disc is full. What I need to know is what is the best and most economical way to go, should I purchase an external hardrive (I have been looking at an Iomega Mini Max), invest in a mini mac and perhaps run Tiger seperately or upgrade software and just run Tiger on my computer or is there another way that is not too expensive?

I would be grateful for any advice.
