Nzbval is a free Dienstprogramm that you can use you test an NZB file against your news server and verify that all of the parts exist before you start downloading. It can save you a lot of time because you can avoid downloading from .NZB files that have missing parts. Missing parts can ruin a download, wasting time and bandwidth, and nzbval is designed to prevent that from happening. If you've ever downloaded a gigabyte or two only to run into missing files that ruin your download, then you know exactly what I'm talking about. Nzbval works with your existing news server, and it is newsreader-independent, which means you can use it in conjunction with any binary newsreader that supports NZB files. Nzbval is free for noncommercial use and is free of nags, expirations, delays, etc.
