I installed Leopard over Tiger the other day, and I guess it did an "archive and install". I say I guess b/c I never made a selection of what to do. The installer just told me how much space I had and how much space would remain, so I figured that was the right way to go. My question is this, though. Did Tiger get deleted? If so, why wasn't that HDD space regained? THis is my first OS X upgrade, so thanks for any info anyone can share about it.
