Sharing large files with remote editors or clients externally

Hi guys,

I work in the media industry and at times we do have to share large asset files with remote editors/clients sometimes more than 100GB, have tried NextCloud & YouTransfer, but some have complained that the download keeps failing, so any advice and help would be appreciated!

I know I can go the VPN route (But I do not wish to expose my server to others) or even p2p file sharing like torrent, but for a one-off type of usage, what would be the best method to achieve what I require and simple for everyday users?

Thank you!
