If you have access to a server, FileShuttle is a free app for the Mac (s aapl) that makes sharing files, images and text a snap. Add your server’s FTP details, and uploading files is simply a matter of dragging them onto the FileShuttle icon in the dock. The file is uploaded and a shortened URL is automatically copied to your clipboard, ready to paste into a tweet, IM or email. Drag multiple files to the icon, and FileShuttle will package them up all up into a handy ZIP archive before uploading. You’re kept informed of the progress of any uploads via a progress bar indicator under the app’s icon and Growl notifications.
As well as uploading files, it can also automatically upload screenshots (in a similar manner to the GrabBox application I wrote about previously) and save snippets of text as text files, making it possible to turn a directory on your server into an easily sharable pasteboard.
A screenshot can’t really show how simple it is to use, so I made a short screencast:CloudApp Droplr
