How do i play Winamp Media Files in itunes?

I've downloaded some music and they show up as Winamp Media Files.

I can set them up so they default open with another program such as Windows Media Player but the actual file type still says Winamp Media File.

I do use Winamp to play all my music and would like to keep doing so but i want to be able to put these files onto my ipod.

I realise there isn't such an extension as Winamp Media File but i don't know what type of file they are or how to find out.

Is there some way i can find out what the file extension is (in properties it just says Winamp Media File) and then can i convert the files somehow so theyll play in itunes and i can get them on my ipod??

Please help.

Anybody got and ideas?

Surely theres a simple way to find out the file type that im overlooking?
