EXT2/3 for windows
Just ran across a really nifty little driver that I didn't know about, so here's a post about it! I've been running dual-boot systems for a while, tend to use Linux for pretty much everything, but it seems like there's always an application or two that I need a copy of windows for. So, I was just working on the windows partition and happened to think "gee, wouldn't it be nice if someone wrote a driver that would make extension 3 filesystems usable to windows?," did a quick google search and wouldn't you know someone's done it already! And, it seems to work perfectly!
So, here's the link.
