Large Number of Files to Recover

I am trying to figure out how best to recover most of my data files on my HD. (How I came to need to do this is a long story. It involves a long list of circumstances with multiple drive failures.)

Right now I'm dealing with 250,000 jpg files. There are lots of duplicate, triplicate, quadruplicate, etc. files listed. About 75% are not recoverable. They vary in size. It's a long list. I don't seem to be able to sort on two or more rows which is making selecting the files to recover very difficult, time consuming, and tedious.

Am I missing something?

As you've found, you can only sort on one column at a time (you're in Advanced mode I guess). You could try setting the View to Tree, which might bring a little order, but if you've run a deep scan then you'll have a lot of files with no parent.
