someone brought me a footage from a cctv (regarding some minor robbery) and is asking me to show him the thief, all I have is a ~1 GB file with no extension, and a windows software (apparently came from cctv) for watching the videos from pc named " processviewr7 "

I can't open the file with this software because there is no extension on file, and I have tried some common extensions but had no luck, what should I do?

VLC media player on Windows does a a very good job of detecting audio/video codecs. If you running a *Nix system, then file extensions are not needed, these systems read the file header to determine the file type.

Have you tried to open the file with a text editor, to see if there are any hints to the file type in the first few lines of the file?

I guess my File was corrupted, I tested with another file and it worked.
