File limits are not only a sender problem
Discord file size limits affect more than the person uploading a file. They also affect members who need to find it later and moderators who have to keep channels usable.
What server operators should consider
Individual Nitro can solve some cases, but shared project files, videos, and reference material are usually better treated as a server resource instead of a personal subscription problem.
The broader workflow is covered in the large file sharing guide.
Separate the sharing workflow before storage becomes painful
DisCoRibute starts with a free allowance, so you can test the server workflow first and upgrade only the servers that need more capacity. The setup flow is described on the help page.
