how do you know what type of files your computer supports?

do you practically have to download something to support different movie formats?
or is there a place you can look and see if supported?

WIndows Explorer>tools>folder options>file types. I think this is what you are asking about.

Not very useful. An app like GSpot will tell you if you need or have the codecs for a vid file, and MediaInfo will give lots of details.

Both free.
