I sorted my photos, and red labeled the better photos.
How can I make a copy only of the red labeled photos to a new folder, and continue to process them (Develop), and maybe delete some from the copies in the new folder?
Lightroom does non-destructive editing, and never changes the original files. Edits are written as text to the catalog.
When you export or print, the edits are applied to a new file, and the original remains unchanged.
So simply edit your red labelled photos, and if you need to use them outside of Lightroom, export copies (usually jpgs) to a folder of your choice.
Copying files in Lightroom is not possible, and there is no need for it.
If you want to create several versions of an image, use Virtual Copies.
I consider the originals as "backups". I planned to copy the selected red labled photos, in order to manage only a subset of photos.
The originals aren't backups, you have create backups manually, preferably to a different disk.
And like I said, you cannot copy files in Lightroom.
Please understand that your images are not in Lightroom, or in the catalog.
The catalog only contains references to the image's location, as well as the edits.

Thanks Per, that is exactly what I was looking for. Still reading...
1: Yes, you can filter on label color.
2: Yes, you can select all these images and then select the menu or the shortcut for creating a virtual copy.
3: You cannot create a virtual copy in another folder. Virtual copies are always shown in the same folder as the original, because they are just a second set of metadata belonging to that original. You can place a virtual copy and its original in different collections, however.
