Thanks for the reply but I am unable to because when I confirm deletion of one picture I did not expect it to delete all the photos in the folder so there are none left to right click on
Then don't highlight all the images before you press the delete key. This is just a user error and user failure to observe what's going on, in my opinion. Additionally, the Lightroom warning should have indicated that all the images were about to be deleted.
Adobe has never said publicly whey they don't provide undo of photo deletion. But you can add your constructive opinion to this feature request in the official Adobe feedback forum: Lightroom: Cannot undo delete | Photoshop Family Customer Community . Be sure to click Me Too and Follow in the upper-right corner. That will make it a little more likely Adobe might eventually prioritize the request, and you'll be notified if they do.
Because like in other programs, you get a dialog box CONFIRMING that you want to delete, and only if you answer in the affirmative does delete actually happen.

That only happens when you have other, All, photos selected in that folder. But in that Confirm Deletion dialog box, at the top, is listed the number of images that will be deleted. And then there is a Cancel button in that dialog box too.
