If you know something about PHP it can do it. Via its function scandir. Let me warn you it is a lot of hoops. Maybe all worth learning though. Things like learning how to make FileMaker output UTF-8 text have to come first. Like I said a lot of hoops to jump through. The Troi file plugin lets you thoroughly test with not that many limitations. The 24U plugin does it well also and both don't seem to totally break the bank. They both do a good job. I have only tested both but I was impressed. The BaseElements plugin seems to do it also but I have not been able to get to testing it. I understand that one if free, I think.
I've mastered The UTF-8 thing thanks to the wonderful tutorial put up by Beverly Voth on FilemakerHacks.
I will look at PHP and BaseElements. Thank you! I've used 24U but I don't have it for current version of filemaker and I'm being a bit stubborn about it, maybe. Appreciate all the suggestions.
Base elements plug in did the trick!
I have related issues so I'm going to post a new thread.
