I should explain my use case a little more. I have many different projects where I use the same basic folder structure. Here is an example, more or less the same as what I actually use:
|-- 1 Original Images
|-- 2 Color Corrected Images
|-- 3 Edited Images (images that have been cut our from their backgrounds, or edited in other ways)
|-- 4 Finished Images
| |-- CMYK
| |-- RGB
I've been using this basic folder structure for a long time for all of the Product Catalogs at the company I work for. Oftentimes, I need to find the final images for a list of particular products, and so I use HoudahSpot to do this. Many of the products are carried over from year to year, and so I do not know which project folder the image I am looking for will be in, but i do know that it will be in a subfolder called "4 Finished Images." At the moment, I have to go through several results for each search and look at the file paths until I find the particular file that I need. If I was able to filter by path, then I could remove this step and about 3/4 of the time that I spend processing these images.
