(This has been fixed. The audio should now be good!)
We're going to start filling in a gaping whole in the videos thus far: Working with Many Files. This is going to be the absolute basic methods for working with multiple files in one of Vim's most important concept - buffers.
Please visit derekwyatt.org to see a better organization of these videos and to make some comments. I'm trying to make that site more of the "go to" spot for these things. Vimeo is a fantastic site, but it's not great at organizing things or managing all of the other information I think we want to cover with Vim.
