Select only recent items in finder
I'm trying to set up an automator script that will run only on recently added (or new) items to the directory. Currently, if I add a folder or file to that directory, Automator will execute the action on all of the files, which I don't want. I can't quite figure out a way to do that other than toggle the option to be "date last modified is...", but the smallest increment is one day, not minutes or seconds like I think might work. Ideally, It would only run on a new item, and run only once on that new item for every item that is added. I have very little experience with Applescript, but I can follow directions like a boss! If any of y'all can help me out, it would be greatly appreciated.
Thanks,
Chase
P.S. - this is my first post here, and I don't quite understand the whole "select a community to post to" option. If this is in the wrong place, or there is a better place to post this, please let me know.
