How can I convert multiple files and save them to a new directory with the same name? I'm talking hundreds of files. Here is the gist of what I am trying to do:

convert *.tiff -alpha transparent c:\differentDirectory\*.tiff

I know the syntax above is incorrect, but how do I correct it? Or is that even possible?

I do not know that you can have a wild card in both the input or output. There may have been a post by Anthony about that or a possible work around. But the easiest way to do this is to use mogrify. see
http://www.imagemagick.org/Usage/basics/#mogrify

cd path2imagefolder
mogrify -format tiff -alpha transparent *.tiff

Note that will override your input images. So to be safe or to test, use -path

create a new folder, then
cd path2imagefolder
mogrify -path path2newimagefolder -format tiff -alpha transparent *.tiff

By your notation I assume that you are working on a Windows computer, such that http://www.imagemagick.org/Usage/windows/#for_loops should provide you with the solution.
