file types i want to download
 

this is probably retard talk, but i used to have windows files that would show up to download and now im getting quicktime files, same file type i guess just diff platform or something, how do i change which ones i get, and does it matter?

It doesn't really matter. It just shows which player you have associated with that file type.

It's easy enough to change. Just open the folder with the files in and right click one of the files > properties > Change > select player you want > OK.
