I moved a whole bunch of old photo booth files from my macbook pro to a hard drive. (It was a stupid move; I thought it'd be a good move to clear out some old files for a "new start at college"... but I was thinking PC terms, not Mac terms, and now I'm totally lost...) Now, a whole bunch of my photo booth photos are missing. All of the files are on my hard drive. Or they should be, as far as I know... but I don't know what I'm even looking for. Which files do I have to save back on my computer and where if I want my computer to recognize the old files again? What do I dooo??
