How do you separate jpeg sidecar file from cr2?

Question

I now see that the preference to treat jpegs as separate files is an import preference.  So now I have some jpeg_+cr2 files that show up in grid view.  Other than going into explorer and deleting it, is there a way to separate and remove the jpeg in LR?

Answer 1

If you shoot jpeg+raw there are two methods for handling files determined by the settings in:
Edit >> preferences >> general (tab)
The box “Treat JPEG files next to raw files as separate photos” is checked
LR will import both copies and show both copies in the Library Grid.
You can optionally stack to avoid clutter so that one thumbnail is displayed for each pair.
Photo >> Stacking >> Auto-Stack by Capture Time
Set the time between stacks to zero so that only those with the same capture time are stacked.
The box “Treat JPEG files next to raw files as separate photos” is left un-checked
Lightroom will add both raw and jpeg to the folder on your hard drive but will only display the raw image in the Library, treating the jpeg as a sidecar.
This is my preferred method because if you use LR to move a raw file the jpeg automatically travels with it. And I have a jpeg in the folder for instant upload to social media, even before I start rating and editing the raw images.
Obviously it’s a personal choice whichever method suits you. But to answer your original question; if you use method one you can use the library filter (press the backslash key and choose text) and e.g. type jpg so that the filter reads:
Any Searchable Files >> Contains All >> jpg
Then try using jpeg
For the second method, you would simply delete jpeg files from the folder but that would break the sidecar link.
