Yes, using HTML5 FileReader API. The best source for that is , http://www.html5rocks.com/en/tutorials/file/dndfiles/.

Scroll down to reading files.

FileReader.readAsText(Blob|File, opt_encoding)

Split the content with EOL character for UTF-8.

Note: By default the string is decoded as 'UTF-8'.

I dont think its possible to access local hard disk. JavaScript doesnt have access.

You can run a local server on your computer and put those files in it. Access it from there.

You can store and retrieve data using localstorage. html5rocks.com/en/tutorials/file/filesystem . But you cannot access anything outside that :|
