In PSE19 Organizer is there a way to select all photos, including all items in a Version Set or Stack? I used the Copy/Move to Removeable Drive option, however, found that photos in a Version Set were not selected for the move. There does not appear to be a way to globally expand all sets or stacks and I would prefer not to convert to individual items. This also affects counts in albums since it's not counting all items.
I think you have met a similar situation to that in which you have the display of the result of a search, showing both individual items and some items included in version sets/stacks. Those are displayed expanded, showing both best match and non match. You can't select only the best matches from the result of that search. This has been discussed from the beginning of the organizer and I have not read or found any workaround.
Unfortunately, that seems to be a fundamental limitation in the Organizer.
You can select all version sets or all stacks, and in the 'View' tab, you can expand or collapse stacks, but not version sets.
As a side note: you are using the 'Copy/Move to Removeable Drive' command. What would be the advantage over using the 'export as new file' command.?
