How can I save a folder with pictures in it, on PC or MAC? (Not Camera Roll)

Dear Apple Community,

I want to save a Folder with pictures in it, that I created from the iPhone.. these photos (and videos) are available only in this folder and I don't want to loose them at all!

Whatever, how can I save this folders on my mac? and/or PC? 😕 And I don't mean the camera roll folder! Just this folder that I created on the iPhone. 🙂

Thanks in advance for you anwers!

Best Regards,

Luke
