Some friends went away and left me their laptop. They have been taking videos and there are some .CPI files they simply cannot open.
Neither can I.
I have Googled, posted on a tech forum, etc. None of the trial of freeware programs that say they can open them DO open them.
According to what I read there are several types of .CPI files - one of them is a high definition file.
Another type is a file associated with hi def but they are 'junk' files, left over from the recording process.
I am thinking that when they get back they should ask a store that carries the camera they are using or the place they bought it.
