Creating folders & moving sets of images into them?

Hi, I'm a newbie & I've made a couple simple Hazel rules that saved me a ton of time but I've got something more complex that I can't figure out how to do (and couldn't find this answered elsewhere here).

Every day I generate several still images from videos of dogs up for adoption and place them in a folder. Each dog has an ID number (example: dog #1 ID number is A4978497). There are several still images for each dog. For example the 1st dog would have an ID number A4978497 and this is how the filenames look:

A4978497-3 F_01 2.jpeg
A4978497-3 F_01 3.jpeg
A4978497-3 F_01 5.jpeg

The 2nd dog might have an ID number A4981214 & would have several still images with these filenames:

A4981214-1 F_01 2.jpeg
A4981214-1 F_01 3.jpeg
A4981214-1 F_01 4.jpeg
A4981214-1 F_01 5.jpeg

I do this process every day which generates lots of images - all of them end up in this one big folder.

What I'd love to have Hazel do is look at the first 8 characters of all the .jpeg file names in this big folder (for example: A4981214) and then have Hazel create a folder named the dogs ID# (example: A4981214) within the big folder and move all that dogs photos (in this case, that start with A4981214) into that dogs new folder.

Does this sound this possible?

Yes. Look up "match patterns" in the help. You can create a custom attribute to grab the ID and then use that in the Sort into subfolder pattern.

Thanks SO much for the tips. I went ahead and looked up everything in the HELP section and I got sort of close but I guess I don't have much of a programmers mind because I couldn't quite get there still. Here's a graphic I made up showing where I made it using your tips and where I'm aiming for. If you have any more tips it would be much appreciated if you have time.

You need to create a custom attribute to capture that first number so you can re-use it later. The help should have an example of that which you can follow.

Thanks SO much! I got it working thanks to your help. A huge time saver.
