Just a thought, and something I do when I can’t remember where I was harvesting something, is to use AG (also called Silver Searcher) to search in the Miqo folder. It is very fast, very easy to install and use.

To use after installing, just use the command line to navigate to your Miqofolder and type something like
ag alumen
or
ag cobalt
You will know what the grid name was (or if you have it) right away.
