The .DDS Texture Files

Hi there, could someone tell me how to read .dds texture files. I can't open them in Adobe Photoshop 7 ???
. I can't open them in ImageTool.exe ???
(comes with Aircraft and Vehicles SDK). What can I use to read them. It's like they are unreadable. That doesn't make since because repaints are being made.
Thanks for any help I get,
Airbrat
