I think that My little Sister would love that. She is really into My Little Pony. I have been thinking about driving into town for the surprise Birthday party that My Family is throwing for Her. I will have to get her something relating to My Little Pony.
That's because it's just a zip. A .wzs file is just a custom zip extension Nullsoft designed to differentiate it from from regular zips when they were designing earlier versions of Winamp. Most versions of Winamp can still use the .zip file, all by itself, though it can also use just the folder, on one condition: that the files within don't get shifted out of their original order. The advantage of the .zip or .wsz format is that it keeps the file order frozen. I've read that it's possible to change the file extension from .zip to .wsz, but I have no experience trying it, so I don't know how it would turn out. Just keeping the zip file should work fine, all by itself, though. It's what I've used on my system for years.
