Personally, I have used that methode.

It's a bit tricky, but if you upload a large file, split it to 200/400MB parts and upload one part to one host. If you have 8 parts, upload to 8 hosts, it's a nice methode to earn a few extra bucks although keep in mind that the downloaders wont purchase premiums on these links because that would just be a waste of money for him.

But, as a downloader I do prefer downloading single links from either filesonic or fileserve, mostly because I have already got myself a premium account on both of these hosts and they are giving me superb speeds and wont let me down when it comes to downloading.

As an uploader I am trying to provide 1GB links, or sometimes i'm splitting them to 400mb+ for the moneys sake
