Why do Winamp 2.x skins download as SZ files?
This phenomena has occurred to several people who have installed Winamp 3.x parallel to Winamp 2.x. It is most likely due to a bug in Winamp 3 and as far as I know applies to Internet Explorer users. I do not know a solution how to fix this. If you like, you can discuss this in the messageboard and thereby give/get help from others, who have the same problem. For now, you can fix the SZ files simply by renaming them to WSZ using your Windows Explorer. Simply change your skins from “skin.sz” to “skin.wsz”. To do this, make sure that your Windows Explorer is set to display extensions of known file types. This can be set in the options under (Win XP: Extras >> Folderoptions >> View >> Hidden Files and Folders). For more help, check out the following thread in Winamp.com’s forums.
