How to make file extensions work for behavior blocking.

When you open a command prompt and type a name it will often start up the appropriate program. However if behavior blocking is on then it plots up with a message that (filename) could not be recognized and requests unlimited access to your computer. Even if you click on ‘trust this application’ and press ‘run unlimited’ it will popup again even when you try to start the same program.
(Example- typing
“C:\Recorded files>Alfred Hitchcock Hour_KETVDT2_2014_11_16_01_58_00.wtv”
it brings up the behavior blocking screen
How do you make it work like clicking on the file in windows explorer (It should just open the file with the associated file). It was the main reason I had to remove Comodo the last time I had it installed.
