I have done searches for various items, such as plugins for various mac apps, and they are downloading with with the suffix .asf at the end of the name. ASF is a windows streaming media format. Whya are they all showing up this way if the plugins are specifically is coming from a mac user and going to a mac user. Also they are being called "limeware documents."

I can't find anything about limeware docs, or how to translate any of these to the original so I can use them. What do you suggest? I would appreciate your help. Thanks.
