The following tutorial will take you through the process of sharing and sending files using the Large File Transfer service.
Log in to the Large File Transfer Service and click the Compose button in the upper left corner of the window.
To attach a file or a folder containing a number of files, choose one of the two paperclip icons at the bottom of the message:
Select the files or folders to upload and click the Choose for Upload button. You are now ready to send your message.
Click Message Settings to check the optional settings available to apply to your message before sending. The default message settings can be seen in the screenshot below. This is also where you can check when your file attachment links will expire and be removed from the Large File Transfer service.
