I've found a similar structure along with a naming convention useful at my day job --- the big thing is the names are such that when copied as a filepath, the filepath and extension deleted, and underscores replaced by tabs, the text may then be pasted into a spreadsheet and summed up or otherwise manipulated.

In somewhat of an inversion, I've been getting the initial naming done by an LLM (well, I was, until CoPilot imposed file upload limits and the new VPN blocked access to it) --- for want of that, I just name each scan by Invoice ID, then use a .bat file made by concatenating columns in a spreadsheet to rename them to the initial state ready for entry.
