How to organize the reception of large files (1 GB+) from clients?

Question

File sharing

Hello! I want to organize the reception of photos from clients in large volumes (1-3GB). But the problem is that most of my clients are very far from IT and from elementary computer literacy. They are not familiar with "dropbox" services, nor with file transfer via torrent, nor with uploading to an FTP server.
Hence the question, how is it possible to organize the reception of files of such volumes as accessible as possible? Roughly speaking, for a person to receive a link and simply select the desired folder.
At the same time, I want to clarify that the hosting on which everything is working at the moment will not allow you to accept such volumes of files, so I wanted to resolve the issue without changing the hosting.

Answer 2

see OpenTrust MFT.
A managed file sharing program allows you to share large files. The transfer is protected by https, and there is also the possibility of encrypting the transferred files. If necessary, you can issue a so-called unregistered user. token - a link to upload files to your MFT server.
