TUF supports the upload of files via HTTPS (preferred and easiest method) and/or SFTP.
Files uploaded via HTTPS will notify the uploader via email that the upload was successful (if the email address provided on the upload form is correct).
All fields on the HTTPS upload form are required. The most important field, however, is the Case Number. If the Case Number is entered incorrectly, TUF will be unable to correctly route your file, and may result in delayed response times and may also require the user to upload the file(s) again.
Files uploaded via HTTPS are restricted to 2GB or less in size. There is no file size limitation for SFTP uploads. For reasons detailed in a
later section, HDS recommends all files be 1GB or smaller.
