Grouping file extensions from a folder

  ragbag 18:50 06 Jun 05

I have a folder which contains several sub-folders on my external hard drive. These hold multiple photos of a subject taken over 5 years (grouped from back-up CDs and DVDs. The file extentions are: .jpg - .tif - .nef (raw) - .tif I would like to simplify matters and just have 4 sub-folders:
How can I gather each group together to achieve this?
