On this topic, actually, that's something I've sometimes wondered about - I know that with ntfs/Windows, you need to occasionally defragment your filesystem because you can get fragmented files (amazing leap of logic there, eh?

). I've never heard of such a need while using Fedora though; does ext*/lvm/Fedora/Linux work in a way that prevents files becoming fragmented, or is it just considered unnecessary despite fragmentation occurring? Or is there something else to it?
