Nowadays, you can share almost anything on Twitter, including sharing videos, and sharing songs. TweetaFile is a free web service to share your files on Twitter. You can share any type of file using this free service, including, PDFs, video files, Docs. To share a file, you need to provide your Twitter username and pasword. Then you can upload the file, and TweetaFile will provide a short URL of the file that can be shared in your tweets. Anyone who clicks on that URL can get a direct access to your file.
Only thing that I don’t like about TweetaFile is that it needs your Twitter username and password before you can share a file. I had reviewed Filetwt a few days back as another Twitter service to share files on Twitter, and it does not needs your Twitter credentials.
