PowerPoint Version:X question

I do this kind of thing a lot because I use video and audio in my presentations. And what I always do now is create a new folder and put all my files in that folder to use with that presentation. So when I change presentations, if the topic is different, I create a new folder and copy all the media files I will use (again) into THAT new folder. I used to do "pack N go" with the PC but still found it unreliable sometimes. I like to have all the files with me on my flash drive just in case . . . I hope this helps!
