Elements 2018 unstack multiple photos

EarlH  wrote I had my camera set to take both raw and jpg images, while on a trip so I could upload the jpg files to a tablet to share with friends while travelling.   When I imported from my camera both the raw and jpg formats were imported.  Being new to elements I then found duplicates and stacked them.  Now I realize I want to delete all the JPG files from the catalog and my hard disk.  I there a way after selecting all stacks to delete the JPG files without having to do each stacked set individually?

I assume the stacking process has resulted in the raw original being the 'top of stack'?

If so, select your stacks, right click for the contextual menu and choose 'flatten stack', which will only keep the top of stack and delete the jpegs.

If the jpegs are 'top of stack', you can't flatten in batch. You would have to use the same contextual menu to 'unstack'.

It's possible to select jpegs in a folder or import batch and to further select jpegs from the menu Find >> By detail >> File type is jpeg.

Delete the highlighted files ('del' key).

Warning, the above will not work if you already have edited jpeg variants of the raw file in a 'version set'.
