NOTE: Tripod has a list of permissible file extensions which does not include .MZ, .BTM, .ION or .DAT files, but it does not prohibit the storage of such files. It just assumes they are HTML files and (sometimes) prepends them with their Javascript to generate floating ads.
This means that your browser will probably display them when you click on them.
To download them, right-click them, select "Save Target As..." and make sure to save them with their proper extension.
You can of course also get the MOZART scores by downloading the .ZIP files, or you can open them in the free MOZART Viewer as described below.
