The publisher of this utility claims that you can save any flash file with one click of the mouse. After testing it for ourselves, we had to make sure they were referring to the same program we tested, because we couldn't get it work at all.
Flashgrabber had an extremely confusing user interface that was half in German and half in English. It contained a blank, white window at the top, and a window at the bottom for displaying flash files in the browser cache. Not knowing where to go next, we clicked on the Help file, only to be taken to an even more confusing, unfinished publisher's Web site. The video menu contained links to popular video-sharing sites, such as YouTube, but they merely took us to the site, nothing more. We thought that selecting a video on YouTube might trigger the program, but nothing happened.
On top of all the problems we had with this faulty program, it comes with a stingy, five-day trial period. But it didn't is that long to rule this utility out as a viable tool for downloading flash files.
