I came across this post: How can I move files and view the progress (e.g. with a progress bar)?
I think its a very interesting question, and the OP criteria for marking the accepted answer makes perfect sense to me, with the exception that the link is dead by now, and nobody has been able to find a working link to a similar, let alone the same, resource. And, as you can see, the whole answer depends on that, now dead, link.
Is there any way to request that an answer could be marked as something like "not usable in it's current state", if you don't want that post deleted?.
