Thank you for your reply to my question Leonie. I do not understand how using 00001, 0002 helps with my problem. What I need is a catalog system that works in a text file mode just like the finder uses. Regardless of when you add a titled file numbered as 1.1b, 1.1f, Ib, 1f, 2b, 2f, thru, 10b,10f. it always stays in the same order. In, as you say, a text file list as in Photos the numbers will come out as 1.1b, 1.1f, 10b, 10f, 1b, 1f, 2b, 2f. Keeping the ones and say twos etc together with the tens in numerical order is necessary for me.
With thousands of pics added at different times, including repeat of original numbers with something like .1 added into the Photos app I was unable to see any difference adding 0000 in front of the existing numbers. Are you saying I just have to have a separate distinct number for each pic. That will not work for me.
If I use another place to store pics I first have to add them to Photos, edit them, title them export them, open in another DB like File Maker create a Image field, Text title field and a Numerical field to sort on. Any idea how finder manages to alway keep the order in what looks like a text field?
