When I edit an image in Lightroom Classic on a PC, it LR creates a virtual copy for each action. This is something new. I don't need or want virtual copies of all my images...sometimes I just want to zoom in and check something, but then I end up with 2 of the same print. I haven't had this problem in the past, so don't know if this was a change occurred because of an update, or did I accidently "turn" on something. Can't seem to find any information on this issue...I know and have known how to create a virtual copy when I want one, but just don't want to take up more room on my hard drive nor take the time to delete this copy.
Virtual copies aren't going to take up more room on your hard drive because they are virtual copies. They only exist in the catalog. Is there any possibility you have enabled soft previews, and that is what is creating all the virtual copies?
Does the virtual copy thumbnail/cell have an indicator to show it as a virtual copy? Bottom left corner, looks like photo being pulled back
Indeed, if you select a soft proof AND apply an edit, you'll get a nice Proof Copy (virtual copy) for those output specific edits. Its a great feature which again, takes no space, holds just these output specific edits and honors the rendering intent selected (which plays a role in what you see) when you move into the Print module.
