The order in which files are processed

If I have hazel process several files in a folder that all match, it will start by alphabetical order. Is it possible to have Hazel go by file size?

There's no way to control that. The fact that is currently goes in alphabetical order is an implementation detail and is probably not something to count on either. Can you explain why you need this?

In one case, I have many files of various sizes in a folder that I use Hazel to process. I have multiple computers processing these files and I want the slower computers processing the small files and the faster computers processing the larger files.

I could think of other times that I want the processing to be FIFO or LIFO.

Sounds like very specialized logic. I think you'll have to write a script to handle that.

That's disappointing.
