How to make NIS Skip Certain Files

I have a couple files on my PC that NIS2011 repeatedly tells me to delete.  However, I know what these files are and I do NOT want to delete them.

 

Delete is the only option in the dropdown box.  So, I just cancel each and every time and this is getting to be a PITA.

 

Is there a way for me to tell NIS to ignore these files or that that are "OK"?

 

Thanks for your time,

Chas
