Batch delete the JPEG's from all my RAW/JPEG pairs?

What's the best way to batch delete the JPEG's from all my RAW+JPEG pairs?

I have a 88k image library many of which are RAW+JPEG pairs. I've got about 50GB's left on my 2TB internal hard drive and need to free up space. I'm combing through the years worth of data attempting to clean it all up but I thought dumping the JPEG's would be a quick and easy gain. Can anyone thing of a safe way to do this? Creating an album of all my pairs is easy enough but I can't find a "delete JPEG" option.

Thanks!

You might be getting the Previews (which are JPEG files) confused with the JPEG masters. Now that you have set the RAW files as master, the JPEG masters are not used. Think about it. Previews are created by taking the master image (whether RAW or JPEG or TIFF or PSD) and applying all the adjustments and edits you've done in Aperture. The Previews must be recreated each time you edit the image.

To be even more confusing, the RAW files themselves have embedded JPEGs. These are used for example in the camera when you view the image on the LCD. Aperture can also use these embedded previews to speed up initial display of RAW files upon import before they are processed.

For significant space gain and low risk, moving to a partially referenced library is a good solution as I posted earlier. I went that way because I have an iMac with SSD and HDD. Works very well.
