It's an easy way when sending files via emails or transferring money through PayPal! I'm using this software as well in my job since years ago but now we still use it at work every day even though there are other more modern applications out nowadays like Dropbox etc., which could have been used instead because they're free too!! The best thing about zippyshare was that before all our clients would send us their images with watermarks so people couldn't copy them directly without paying royalties first; however after switching everything over into dropbox (which does not allow users access if someone else has already uploaded stuff) those problems stopped immediately.
