“Windows Vista introduces the Preview pane in Explorer, which shows the contents of the currently chosen file. You can also play multimedia files from the Preview pane, without opening Windows Media Player. This article explains how to use the PreviewConfig utility to register a custom file type for the Preview pane in Windows Vista Explorer.
Registering file types for the Preview pane
If you have a custom file type and wish to register a plain text or a multimedia Preview handler for the custom file type, you can do so using this utility.
With this free, simple and easy to use utility you can tweak how files are handled by the Preview pane in Vista/Win7. It would be hard to make this any easier… ;)
And it doesn’t even need an install. Download it, unzip and run it (with admin priv’s) and you’re good to go.
