From IQ Storage DBA ShareByLink:
Upload and make sharing links to your files. ShareByLink is a free file sharing tool that's extremely easy to use. Just right-click files and select 'Share online using ShareByLink'. Files are uploaded over a secure HTTPS connection, and stored on ShareByLink.com's servers for 30 days, allowing you to share files easily.
Large files are streamed, and the sharing link is provided instantly, allowing you to share big files right away.
Another way to share files is to double-click the ShareByLink icon on your desktop, and drag and drop files into the ShareByLink window.
Optional: Computer experts can install ShareByLink's PHP code on their own server for increased privacy.
