I can only upload one file?

Yes, at the moment, due to the limitations of html, it is impossible to upload folders directly. However, if you upload an archive (.tar, uncompressed) and toggle the option "Extract archive" the torrent will contain the files of this archive, under a subdirectory named after the archive (minus the .extension part).

I uploaded a file, what now?

You can share it with your friends, of anyone, if you give them a link to this page, to the torrent. You should also start the torrent into your favorite torrent client, this way, you will be able to share it. If you don’t do that, the download speed for the people who want download the file will be smaller.

How do I delete a file if I don’t want to keep sharing it?

You have to go to the page for the file and enter the deletion password into the box at the bottom of the page. If you don’t have the password, we have no way of knowing if you are the initial uploader (because this service is entirely anonymous) and therefore we will not be able to comply with your request.
You should also understand that because of the way the torrent network was built, the file cannot be remotely deleted on the computers of the file-sharers. So while the file is gone from the website, it might still be shared and accessible via a saved torrent file or magnet link.
