Tell if movie has been played?
Is there a way for applescript to look at folder with jpg and movies. And mark the ones that have never been played? I was thinking of comparing date modified to date last opened.
There is no guarantee that 'opening' a movie results in it being played.
There doesn't appear to be any direct way to read a file's access time via AppleScript, but you can use the shell commands to find the last access time of a file:
# ls -ul /path/to/some.mov
which may differ from the last modification date ( ls -l /path/to/some.mov )
But there may be many reasons why a file is accessed which does not involve the movie being played, so it may not be helpful.
