Here is an application that lets you access damaged Par files downloaded via Usenet. It is the best solution for this purpose with support for other cool stuff. Most Usenet users battle with corrupted files because the system (Usenet) typically encounters errors while downloading files. Once the downloaded Par file you downloaded through Usenet is damaged, it is impossible to access the contents of the files. However, here is a solution that lets you access and uses those damaged downloaded files. This app makes use of a correction algorithm to fix the damaged files so you can access them. An “auto repair” feature fixes all the files have their blocks available, but they are incorrectly named or broken.
Also, this app can create parity files to divide the main sources to multiple sizes for each data block. You can configure the different processes of this app to run automatically while still monitoring everything that happens. It is also possible to configure the deleting actions of this program so that it removes the damaged and PAR2 files after recovery. The interface of this program is quite intuitive, but, it may not be easily understood by less experienced users. Many options can be customized on this app, and it works efficiently for its purpose.
