concerning *.nfo files

[Yaramir]

I have only recently began exploiting this gamecopyworld.com, and am finding its assistance helpful. Due to my being new to this site and this "world", I have a question that might seem too primitive, but please excuse this.

The questions concerns *.nfo files. I have downloaded numerous archived files containing various utilities I searched for, and all of them had a *.nfo file. However, upon extracting this file and attempting to open it, I received a message that this file is corrupt, and this not possible to open. This was so with all of the files, all of which I was able to open by utilizing Wordpad. Is this what I am supposed to do? It says these are MSInfo files, but I've not heard of such files, or a program that would specifically work for them, before.

I suppose there is no harm in continuing to open this files with Wordpad, but curiosity insists that I investigate this matter. I would appreciate any assistance.
Thank you.
