A very useful option, that is usually included in many applications like download managers or torrent clients, is the one that allows us to preview the video files that we are downloading. In those cases in which this task isn't possible from the mentioned applications or in those that the file is damaged, you can always use Avi Previewer.
Watch videos even if they're damaged or incomplete
Thus, with Avi Previewer the user can, first of all, fix videos that are incomplete or that have some damaged data so that we can later play them using a utility such as Windows Media Player.
Once you have solved the errors of the videos that you have loaded in the application, you will be able to view it from the program's main interface, using the player that has been set as default on your computer.
In what refers to handling it, it is very simple. All the options use the same interface. Once the videos that we want to recover have been added, all we will have to do is press the “Fix File(s)” option.
