Very poor results is what I would expect. I can't explain the crashing 
but I'm not too familiar with the X! Tandem code. You can batch process 
pretty much anything with xargs/ls (downloadable from the GnuWin32 
project). A command like:
ls c:\path\to\waters\sources | grep ".raw" | xargs -n 1 -t masswolf 
--mzXML <options>
should do the trick. The "sources" directory above would contain one or 
more Waters .raw directories - the grep part is to filter out anything else.
