First, you choose the file or folder you want to send and upload it to FileWhopper to get a price quote based on file size. After that, either upload your data directly from your browser (this option is only available for files under 20GB) or download a tiny app that will facilitate the upload (this option is available for all FileWhopper data transfers). You set a password and get a link to the file/folder you uploaded, which you need to copy and share with the recipient. The recipient will use the link and password to download the file/folder directly from their browser, or via a tiny app that will delete itself once the download is complete.
