I'm not sure there are any more .pka files other than the Cisco Packet Tracer files, but you would need to have that app to use the file. Packet tracer is a network simulator for students in the Cisco Networking Academy.
Either you are using the wrong program or they are corrupted files.

HOW TO OPEN AIO FILES
If you mean the .torrent files, then they can be deleted by deleting your internet cache or simply deleting them IF you downloaded them (I like to Open them so they save to my internet cache) Or if you mean the files you downloaded, you can open/watch/listen to it and then you can easily delete it from utorrent by deleting both files (Torrent + the files (cant remember exact)).
pKa=2.86
depends what program some programs can open files that were not created with that program but if the person has no programs that can open the file they cant open it
