I didn't want to step on what Flak said because he's absolutely right. But, if you close bryce to try to deal with the temp files and you can't open any of them you may never be able to resurrect the original file. If you get enough space free to save the file and it goes great. If you can copy everything and paste it into a new bryce scene you usually loose the thing that was messing up the file in the first place and then you know not to use it again or do it differently. If bryce has already been turned off your only alternitave is to look in the temp files and see if you can reopen them. A big hard drive is whatever you can afford. Generally you have older smaller drives disappear and bigger ones that are more expensive come in. The newest ones will be real pricey and sometimes have reliability issues. You will have a price range where you double in size and the price doubles. Eventually you reach a size where double the size costs more than double the price. I like to buy just under where this cost starts to curve up. Right now it seems to be 160GB. I have a year of serious work on mine plus junk and still have over 100GB free. Thanks for the mention. It's great when it happens. Unfortunately I'm in the surf galleries OR work and eat mode for the moment so I missed it when it came out.
