Windows Vista introduces a Preview pane in folder view, using which you can preview image and text files, and play multimedia files from the Preview pane. PreviewConfig is a utility that gives Vista users the power to add file type support to the Explorer preview pane, which can be activated via "Organize." Though the preview pane can be an interesting and useful feature of the OS, it really lacks in file support. It's possible to add support for more without a 3rd party program, but that requires some risky and time-consuming registry tweaking.
