Is it possible to "upload" a file only with client side ? (no server involved)

Question

I am trying to do a simple thing:

Let the user choose a txt file, and save its context to be used on the client side only. no server side needed.

Is it possible ?

Thanks.

It is possible to do so with HTML5 Files API as explained in these resources:
