A huge range of services for Twitter users continue to roll out. Here are two for file and document sharing that may be of use depending on your needs plus an extended list of Twitter tools for music sharing.

FileTwt for file sharing.

Via ReadWriteWeb:

"At the moment, the UI is a bit clunky and the file sizes are capped at 20MB, but the service presents an exciting opportunity nevertheless…it already allows for mass sharing (either via public streams or multiple-recipient DMs) of files, which is awesome news for self-marketing musicians, who desperately need better online promotional tools…"

"Filetwt is now uploading files only to RapidShare. They plan to add more hosts, namely DepositFiles, FileFactory, and MegaUpload, in about one week."

TwitDoc for document sharing.

Via TechCrunch.

"TwitDoc is launching what appears to be the first service for sharing documents over Twitter, bringing support for PDFs, Microsoft Office Documents, and a bunch of other file formats. The site has integrated with popular document sharing hub Scribd to make the process as painless as possible – it only takes around 20 seconds to send a document, and you don’t have to sign up to get started."

Though a bit dated, this list of tools for sharing music on Twitter is also well worth a look.

I'm planning to start featuring more such tools for Twitter as well as other web services with a focus on music marketers and indie musicians in a new category called Indie Music Tools.
