The other day, a friend of mine trying to free up some space on their computer asked me if I knew how to delete the JPEGs from a RAW+JPEG pair in Lightroom. After scratching my head on that for a while, I threw together a Powershell script to do the job, and so I’m sharing it here in the event it might be helpful for someone else.

WARNING: Advanced computer stuff ahead.

This script is for Windows and requires Microsoft’s Powershell environment to execute. I’ve tested it in Powershell version 3 on Windows 7. If you don’t have Powershell installed, the latest version can be downloaded from Microsoft.

To run the script, place it in the top-level directory of the directory tree where you want it to scan; right-click on it and choose “Run in Powershell.” The script will prompt you before running whether you want to just build a list of files to remove or delete them. I recommend not deleting files on the first pass, just to be safe as the deletions done by this script aren’t reversible.

The script considers a JPEG to be part of a RAW+JPEG pair when the files have the same name but a different extension (.nef, .cr2, or .dng for raw, and .jpg for JPEGs), and exist in the same directory. The script recursively scans through every child directory starting from the directory the script is executed from looking for RAW+JPEG pairs.

Results are always logged to raw&jpeg.log in the same directory as the script itself.

Due to the nature of the process, the script can take some time to run, and doesn’t display progress unless it finds matches.

I recommend running the script and verifying that the files it’s selected to delete are in fact RAW+JPEG pairs, before deleting them.
