I'm pretty new with linux, I've played around with a few other distros (beatrix, SuSe, and Knoppix STD just because). Now I am looking to get more into linux as a primary OS (running on a older Windows XP computer).
I just downloaded KNOPPIX_V6.2.1DVD-2010-01-31-EN burned it and it works great on the computer that I'm running it on. My question is, as i was going through the applications I saw that I can install it to a flash drive. To do this do I just plug in my flash drive and go? If so, will a 4GB drive work or will I a bigger flash drive? Also will i be able to save downloads to the drive with knoppix installed on it?

Thanks in advanced,
Travis
