Original photos in Lightroom (do they need to stay on the computer)?


I have found a folder within my Lightroom catalogue called originals taking up a fair bit of room, they are also showing all new uploaded photos in my ‘recents’ on the laptop .. while editing do these NEED to be kept, if they are deleted will the files themselves be deleted, I of course have the raws on a hard drive but wanted to know if deleting these would cause an issue during the editing process? Pic of folder below . When I delete them from that folder, the moment I edit them they pop back into that same original folder again?
