It did the job I wanted it to, but made it quite a bit harder than necessary. I was batch converting files. If you select a bunch of files and click "convert", nothing happens. Instead, I discovered you have to double click one of your selected files. My files were on a CD, and espresso ray offered to save the file on the original, write-only, media, which is not helpful. If you forget to change the save location and try to save on the cd, it tells you that (fair enough) but then doesnt remember the location of the files you had just laboriously navigated to deep in the dicom directory structure, so you have to laboriously navigate to them all over again.
