Removing "+JPG" from Lightroom Thumbnails

Question

Hello,
I've been shooting RAW+JPG on my 30D and importing them both into Lightroom. There seems no point in using JPG with Lightroom, so to save space I now want to shoot in just RAW.
To save even more space, I want to remove/delete the JPG's that I shot alongside my RAW pictures which are now stored on my hard drive. The problem is that if I delete the JPG, the RAW thumbnail still has "+JPG" in the extension. (Example: 20071113_001.CR2+JPG)
What do I need to do to update the filename in the extension so it doesnt show the associated "+JPG" which does not exist anymore?
I've searched several online forums but can't seem to find the answer to this problem.
Thanks!

Hi Dom,
You could do it using the save metadata approach or the SQL approach (might be a bit quicker).
SQL method
Download SQLite Administrator (free) from http://sqliteadmin.orbmu2k.de/ and unzip it to a folder on your hard drive.
Make sure LR is closed and make a copy of your catalogue before you start.
Start SQLiteAdmin, then from the menu select Database>Open. In the Open Database dialog box change the Files of type to Any File, then locate and open your LR catalogue. Ignore the left panel, which lists all the tables and indexes in the database, you will be working in the right panels - SQL Query and Result tabs.
To begin with, copy and paste the following query into the SQL Query tab:
select count(image) as jpegSidecars from Adobe_imageFiles
where lc_idx_filenameExtension='jpg'
and importHash is null;
Then press F9 to Execute with Result. This will give you a count under the heading jpegSidecars in the Results tab. It is a count of the number of jpegs in the catalogue that have been imported along with raw images.
If you want to see the records, you can copy, paste and execute the similar query:
select * from Adobe_imageFiles
where lc_idx_filenameExtension='jpg'
and importHash is null;
Instead of counting the database records, this will list them in the Results tab.
So far, this is just information and has not altered the catalogue. The next SQL query removes these records from the catalogue - there is no going back after this (except with your backup). Copy, paste and Execute without Result (press F8) this query:
delete from Adobe_imageFiles
where lc_idx_filenameExtension='jpg'
and importHash is null;
This will only delete the sidecar jpegs, not jpegs that have been imported on their own.
Once this has executed, close SQLiteAdmin and open LR to check your catalogue.
You should see your raw files without the +jpeg sidecars. You can also now import your jpegs as separate files if you wanted to.
As far as I can tell, this is all that is needed.
Good luck
Tony
