Here's what I'm asking: After I've installed the Live packages, can I delete the white package folders to free up space? Or, do those packages contain the files themselves? The reason I'm confused is that I saw my HD space shrinking as I installed the packs, which leads me to believe that their contents are installed somewhere else on my computer. I realized this is a pretty dumb question, but I don't have the money to spend on an extra HD right now, and I felt like it was necessary to install Live on my computer itself because I don't always have my external with me.

These files (in the right window) are what I'm referring to. Can someone shed some light? Thanks.
