I think I know how to connect an iPhone to the PC (via USB cable). But I am not sure if I can create a folder on iPhone to copy all these files. The iPhone has about 70GB free so that space is not a problem.

Ah yes -- I too have recently gone to the dark side and bought an IPhone (still have my android as well though). Best bet is probably VLC --- https://apps.apple.com/us/app/vlc-media-player/id650377962

You can copy the files to your icloud account too from your PC :)
