Downloads.... Help?

Im new to this but not new to FS. I have FS2002. I've just downloaded a British Airways Boeing 737-400 colourscheme into my aircraft folder but I can't see it in FS. I think its because its showing as a Zipped file. Anybody got any clues as to what I do once I've successfully downloaded files from Flyaway?
Thanks for your help.

Well for repaints unzip the files to a temporary folder ie create a folder called repaints on your desktop.

In a new window oper C:\\....route to your MFS folder\aircraft\737-400\ and place the textures folder in there as a new texture folder, might have to change the number. This will be creating a folder as an alternative repaint for the 737-400. Just close them and run FS, select the 737-400 and then select the type of paint scheme and thats you ready to go.

Same applies for all other aircraft.
