Mysterious folder created

Hello, I have Windows 11. On my F: drive there was a "pictures" folder. At some point on F: a subfolder was created mysteriously. The "pictures" folder is now under the subfolder F: Lightroom cannot find the pictures because of the change in the path. Is there a way to remove the subfolder F: without deleting the files in "Pictures"? Could I migrate the Pictures en masse past the subfolder F; onto the drive F:?
